Cyber-Vulnerability Sees the Light of Day

f anyone ever doubted that cyberspace is also a battlefield, that doubt should be permanently erased by the recent incident involving Google and China. What initially looked like a human rights/political squabble has revealed an underlying, ongoing technical struggle for national security. It is no coincidence that the United States now has an official U.S. Cyber Command, organized in October of 2009 under the United States Strategic Command and led by the National Security Agency The really scary aspects of this incident that came to light along with the dispute between China and Google have been known to computer security specialists and network technical types for some time. This is, however, probably the first time that the dangers of cyber attacks on our infrastructure have been solidly brought home to the general public outside of Hollywood. And that is, to quote H.G. Wells, that “intellects vast and cool and unsympathetic were regarding us with envious eyes.” What has been known and talked about in only hushed tones for years is the ominous fact that there is an ongoing effort by a number of national governments, among them China, to compromise network security in an effort to gain industrial and classified information and to probe sensitive infrastructure, including the power grid, water, sewage and other systems for vulnerabilities that could be exploited for a potentially devastating attack. This is not some kids running on pizza and Jolt Cola trying to amuse themselves, but nation states directly funding battle in cyberspace by PhD-level computer scientists to gain an advantage that could be exploited at the outbreak of hostilities. It directly affects the design and development of connected embedded devices in all fields because things are now so intimately connected and that connectivity is increasing at a furious rate. That is why we brought four CEOs together from four leading companies involved in security for connected devices. It is our hope that their insights will both inform and motivate our readers to increase awareness of security issues involving the very heart of our technical infrastructure. In terms of the Cyber Command, the effort is primarily defensive, but there is also a program to develop offensive capability as well. Just who should authorize an attack and when is

not yet clear. For example, when does an effort to defend a U.S. military network cross the line into offensive action and what are the implications? Also, it has been pointed out that there is currently no medal for technical expertise or action like there are for valor and achievement in traditional military skills, so is the military mind-set really the best qualified for this mission? Well, at least something is being done at this level and it appears that the concerns for commercial security, such as spying on domestic companies in search of industrial secrets, are being left to the Department of Homeland Security. Securing network devices will never be absolute. With the proliferation of smart phones and mobile devices, the entry points for an attack multiply exponentially. It is also somewhat ironic that the technologies that can be used to monitor for intrusion can also be used intrusively. For example, not much is known by the general public about the technology of deep packet inspection (DPI), which is essential for tasks such as network maintenance as well as for monitoring traffic for unauthorized access and security. But that same technology can be used for monitoring “private” communications, which was apparently done in the Google incident in the effort to access the Gmail accounts of dissidents. DPI technology is now sufficiently available that anyone with the necessary technical expertise can use it for whatever purpose they please. It can track terrorists as well as cheating spouses. Industrial installations do really need to have their enterprise networks talk to their automation networks for a host of businessrelated reasons. But while a manufacturing operation could theoretically be isolated from the Internet, no business would dream of trying to so isolate the enterprise network, and that forms what is at least the easiest gateway for intruders. All kinds of technical strategies and policies are constantly being applied and must be applied to protect vulnerable assets. A good deal of it will remain in the shadows, but many aspects must be discussed in public at as technical a level that will not compromise security while (another bit of irony) serving the goal of actually creating and deploying the needed technology. As a publication dedicated to the developers of embedded and connected devices of all kinds, RTC will be a source of ongoing coverage of developments in this area. RTC MAGAZINE FEBRUARY 2010

INDUSTRY

INSIDER FEBRUARY 2010 Companies Collaborate on New Embedded I/O Expansion Standard Diamond Systems has announced that a group of companies in the global board-level embedded computing market will jointly launch a new embedded system expansion standard at Embedded World 2010 in Nuremberg, Germany on March 2, 2010. Other members of the Consortium will also be announced at that time. The new mezzanine-style standard, originated by Diamond, defines a highly compact, low-cost way to add application-oriented capabilities to single board computers (SBCs), computer-on-module (COM) baseboards and fully custom embedded electronics. Diamond claims the standard to be highly synergistic with existing and emerging bus, I/O, chip and board-level technologies. Additionally, the standard leverages the latest high-speed serial expansion standards and is suitable for use with both x86 and RISC architecture host processors, the company said. Following its initial public announcement and demonstration, Diamond will transfer ownership of the new embedded I/O expansion standard—including its specifications, trademark and logo—to a suitable standards organization, the company said. Thereafter, the standard itself will be usable by anyone without charge; however, rights to the use of the logo in association with products will be restricted to members of its parent organization Key features of the new standard will include: • Compact, low-profile form factor—three-fifths the size of a credit card, and one-third the size of a PC/104 module • Single low-cost connector that integrates all host and external I/O interfaces • Provides up to 100 I/O points per module and leverages industry-standard buses such as PCI Express, USB and I2C • Host form factor and processor agnostic—coexists with PC/104, SUMIT, Qseven, ETX, XTX, COM Express, etc. • Multiple I/O expansion modules may be present within one system • Open industry standard • Rugged and reliable Among the benefits expected from the new standard are: • Shorter time-to-market • Reduced board-level development costs and risks simplifies system design • Eliminates cables, resulting in higher reliability, lower cost and faster assembly • Enables scalable and reconfigurable system design • Enables easy product upgrades • Protects from component obsolescence and encapsulates intellectual property • Suitable for SBCs, baseboards and proprietary all-in-one hardware designs • Ideal for rapid-prototyping through high-volume applications • Appropriate format for silicon vendor reference designs • Open standard to increase market acceptance

Intel and Micron Team on 25nm NAND Flash

In an effort to remain a full process node ahead of other NAND flash manufacturers, Intel and Micron have announced that the companies’ IMFT joint venture has now introduced a 25nm 64 Gbit MLC NAND chip. This translates to 8 gigabytes on a single chip. With a die size of 167 mm², the device can fit into a

8

FEBRUARY 2010 RTC MAGAZINE

standard TSOP package. At a die size of 167 mm², a 300 mm fab should be able to manufacture just over 400 dice per wafer. This gives a manufacturing cost of about $4.00 per chip, or $0.50/Gbyte. Compare this to a more common 45nm MLC NAND on a 300 mm line, which should cost about $1.75/ Gbyte. Since the price of NAND flash has been hovering around

$2.00/Gbyte for the past year, and seems poised to continue at that price through 2010, the 25nm process is expected to give the companies a significant margin boost over their current 34nm chip whose cost we estimate at $1.00/Gbyte. The companies made it very clear that they do not plan to drive prices down to follow cost. Instead, we can expect for Micron

and Intel to continue to charge market prices and simply pocket larger margins than their competition. Both companies are currently sampling to select customers and controller makers. Both also remarked that this was one further step that would help bring SSDs into the mainstream. Not only will this new process allow Micron and Intel to profit more than their competition, but it also allows them to squeeze more gigabyte production out of their Lehi and Manassas lines before having to equip their new fab in Singapore.

China’s Landmark Electronics Partners with Sealevel

Sealevel Systems has announced that Landmark—a Chinese system integrator, distributor and OEM of embedded computer systems and associated products—has joined Sealevel’s SeaPartner network.

VPX Marketing Alliance Grows and Introduces Online Product Directory

VITA, the VME Industry Trade Association, has announced it has grown membership of the VPX Marketing Alliance to 23 leading companies in the embedded computing industry. The VPX Marketing Alliance is focused on the advancement of the VPX family of technologies, which includes VPX, VPX REDI, OpenVPX, as well as other related activities on the VPX roadmap such as fiber optics and RF. The Alliance (www. vita.com/VPX ) is continuing the work done by the OpenVPX Marketing Working Group in promoting OpenVPX and in establishing an ecosystem of interested parties who will promote the VPX architecture to drive widespread adoption of the VPX specifications and technology. The VPX Marketing Alliance also announced the availability of an online VPX/OpenVPX product directory (www.vita. com/proddir/productsearch.php). The directory provides the latest information on VPX products introduced by Alliance members. The list of products in the VPX and OpenVPX categories is growing each week as new product announcements are made. VPX is a broadly defined technology utilizing the latest in

a variety of switch fabric technologies in 3U and 6U format modules. OpenVPX is the architecture framework that defines systemlevel VPX interoperability for multi-vendor, multi-module, integrated system environments. The OpenVPX framework delineates clear interoperability points necessary for integrating module to module, module to backplane and chassis. The OpenVPX framework recommends but does not specify development systems to assist in VPX system evaluation, prototyping and development. OpenVPX will evolve and incorporate new fabric, connector and system technology as new standards are defined.

Sleep Can Be Deadly

ack in the old days, when people used the word “control” after embedded, there weren’t a lot of options for powering an embedded system. Power was distributed to all system components, including sensors, motors and electronics at appropriate voltages, and with appropriate sequencing, when the system was powered up. All elements stayed powered up until power was removed. Many systems ran 24/7 for years. These systems ran the gamut from industrial controllers running a printing plant, to patient monitoring systems, or weapons targeting systems. Power consumption issues were pretty much relegated to the few battery-powered applications. In this last decade, we’ve seen growth of embedded (dedicated) applications that only need power when interacting with an operator. The check-in kiosk at the airport, or cash register need not be powered 24/7. In response to the green initiative there is more focus than ever on saving power. There are two elements to saving power in an embedded system. First is the use of low-power electronics. While RISC CPUs have been offering low power for years, Intel architecture (x86) processors and chipsets have finally got some skin in the game with the new Atom family of processors. Nano and Geode processors are designed into some low-power applications as well. The second component of saving power is to put the system into some form of hibernation or sleep mode when in an idle state. Because of the focus on battery life in the laptop markets, x86 systems have a highly developed set of capabilities for sleep modes. However, until recently, most embedded implementations of x86 architecture failed to provide all the hardware and software support necessary to engage a full range of sleep modes. This is starting to change. Hibernation / sleep technology is driven by the ACPI Specification. While ACPI contains substantial complexity with regard to how hardware and software should respond in various sleep modes, the overriding architecture is simple. There are five system-level states, ranging from on (full power) to off (no power). Well, not quite. Off doesn’t really mean off. This is the “soft” off you get when you shut down Windows. The power supply is still alive—in a very low-power mode—providing trickle standby

10

FEBRUARY 2010 RTC MAGAZINE

power for the chipset to sense wake-up events. Waking up from soft off requires a reboot—not a particularly speedy endeavor. The three intermediate states trade off power savings against the time it takes for a system to wake up. In general, the more power you save, the longer it takes to wake up. Simple power saving actions such as turning off a display, or stopping disc rotation, save a small amount of power but wake-up is almost instantaneous. Saving the state of a system to disk requires a much longer time to wake up (the famous Resuming Windows progress bar on your laptop), but saves much more power. An interim step, saving the state of a system to RAM, saves somewhat less power (since memory must remain powered), but restarts much more quickly. Unfortunately, this step requires conscious steps early in the design process with regard to the memory power plane, and has frequently been omitted from many embedded SBCs. If this approach is of value for your application, seek CPU boards offering ACPI State S3 (Suspend-to-RAM) support. An even more gnarly problem revolves around the set of actions that can wake a system from sleep. A keyboard or touch screen press or mouse movement are common and frequently supported wake-up events. Wake on LAN, however, in which a system wakes to respond to a message over Ethernet is much spottier. It requires support in the network controller hardware along with support in the Ethernet driver. And if you want to wake in response to activity on a USB device, we wish you the best of luck. You’ll need it. Green is good. More importantly, green sells. Embedded designers everywhere are finding reduced power consumption as an important feature of new systems. Go for the new, lowerpower processors and chipsets. But before you start factoring hibernation or sleep modes into your application, be very certain that your application can sustain long response times to wake-up events (i.e., probably not for almost any real-time control system), and that your project can accept a longer design cycle, higher product costs and potentially order of magnitude reduction in the set of off-the-shelf SBCs and I/O cards you may choose from. Sleep if you must, but don’t let Prince Charming get too far way. You may need him.

The intention here is, of course, to drive the use of the x86 architecture into ever smaller and more deeply embedded applications, and would at least appear to be aimed at moving into the spaces currently occupied by low-power ARM architectures, for example. If Intel is indeed moving in this direction, it has a big weapon on its side in terms of the available development tools and the armies of experienced developers who are already familiar with x86 and its development environments. It will also be appealing to the desire to use a single architecture for a range of products without having to move to a different one, for example, when you want to develop a handheld version of a given product. Moving a medical ultrasound device from a cart-based version to a somewhat lower performance handheld model could be done with the same developers, tools and probably much of the same code. The cost savings in time-tomarket, R&D, verification and personnel would be significant. For example, when management wants to move engineers from one project to another, it helps if they are already familiar with the processor ecosystem to avoid the delays caused by learning curves.

The 2010 Core Family Debuts

When Intel announced the 2010 Core family at CES on January 7, there was a rain of product announcements that same day based on the Core i7 and i5. These were on form factors as diverse as COM Express, XMC, 6U CompactPCI, VME and VPX and more. Almost half of the new products presented in the Products and Technology section of this issue of RTC are based on the new family. Still others are Atom-based products. So something seems to have gotten people’s attention. Among the features of the family that complement the basic x86 architecture are first, a range of offerings in terms of power budget and the associated mix of capabilities, such as the proportional amounts of compute vs. graphic processing ability. In addition, features


editor’s report

have been brought over from Nehalem that can be quite useful to embedded developers. These include Turbo Boost and Hyper-Threading along with vPro remote security, maintenance and management technology. In addition, Intel has tailored four versions of the family to include error correcting code (ECC). These are the i7-610E (2.53GHz, 35W), the i7-620LE (2GHz, 25W, the i7-620UE (1.06 GHz, 18W) and the i5-520E (2.4GHz, 35W). The processors all come with BGA packaging, which aids the structural integrity of board designs and reduces package size. Intel has announced a minimum 7-year extended manufacturing life cycle for these processors (Figure 1). In addition, Intel has introduced the QM57 mobile “chipset,” which is now a single device called the Platform Controller Hub (PCH) for a two-chip solution, for use in mobile and embedded applications. The memory controller hub is now integrated inside the processor. The PCH supports the vPro Technology as well as 14 USB 2.0 ports, eight PCI Express ports, Gigabit Ethernet PHY, 6 SATA ports and a host of video and audio ports. Turbo Boost is a hardware technology that takes into consideration the computing load on the processor and the processor’s power budget. In a two-core processor, for example, when one core is inactive or underutilized, the processor can determine this and increase the clock frequency by one or two predetermined increments—more if the second core is completely inactive, less if it has some activity, but is not fully loaded. At that point, both cores run at the same clock speed. If the computational load on one of the cores increases to the point where it could exceed the temperature, power and current limits, the processor will step back the clock frequency to remain within specifications. It is possible for an enabled operating system to request the highest allowable performance state, in which case, the amount of time the processor spends in that state will depend on the work load and operating conditions. The processor constantly monitors the power parameters and adjusts itself accordingly.

According to Jensen, TurboBoost is a help, but the real payoff will come when developers begin to optimize their code to take advantage of multithreading. Multithreading is enabled by the Core family of processors on two levels. First, it is possible to implement multithreading between the two processor cores on each die. Beyond that, using Hyper-Threading technology, each core can implement what appears to the operating system as two logical processor cores, each of which can run multithreaded code for a total of four threads running simultaneously on each processor chip (Figure 2). To do this, each logical processor stores a complete set of the architectural state (two on each physical processor). The architecture state consists of registers including the general-purpose registers, the control registers, the registers belonging to the advanced programmable interrupt controller (APIC) and other machine state registers. Interrupts sent to a specific logical processor are handled only by that processor. Intel says it was able to implement this Hyper-Threading technology with only a 5 percent increase in relative chip size and maximum power require-

ments. Balanced progress between threads is ensured by buffer management that ensures that no logical processor can hog all the resources when two active threads are executing. In addition, partitioned resources can be recombined when only one thread is active. Intel’s Joe Jensen stresses his conviction that, “If you go to the code base for embedded customers, by and large, it’s single-threaded.” In order to take advantage of multicore multiprocessing and especially Hyper-Threading, Jensen argues that, “More and more, we’re seeing code developed for PCs with multi-threading in mind.” He maintains that embedded developers need to optimize their code for multi-threading and when they do they will get, “a ton of performance without having to increase power or go to a more powerful CPU.” Of course, one of the main challenges in scaling multicore for the future is that of migrating programming tools, build environments and millions of lines of existing code to new parallel programming models or compilers without having to rewrite vast amounts of code. One tool available from Intel is called Ct for Throughput Computing. RTC MAGAZINE FEBRUARY 2010

editor’s report

Ct is a standards-compliant C++ library that works with any standard C++ compiler—with a lot of runtime behind the scenes. Initializing the Ct library loads a runtime that includes the compiler, threading runtime, memory manager—essentially all the components one needs for threaded and/or vectorized code generation. Ct code is dynamically compiled, so the runtime tries to aggregate as many smaller tasks or data

parallel work quanta so that it can minimize threading overhead and control the granularity according to runtime conditions. The Ct dynamic engine provides inter-procedural traces to compile, which is extremely useful in the highly modularized and indirect world of object-oriented programming. Another toolset is the Intel Parallel Studio, which works with Microsoft Visual Studio for C++ development. Within

Parallel Studio are tools to identify the areas in applications that can benefit most from parallelism and provide step-bystep recommendations for getting there. Advisor Lite extends the capabilities of Parallel Studio by safely modeling, measuring and testing parallel ideas before committing them to actual parallel code. There is also a Parallel Amplifier to find spots where cores are underutilized and/ or locks that may block threads when cores are available. And there is a Parallel Inspector for finding bugs that occur due to the increased complexity of multithreading. The actual implications—both in terms of technology developments as well as competitive market position— are not yet determined, but such a large roll-out heralds what appear to be very ambitious plans for the future of the desktop, laptop and mobile computing arenas, which will make these technologies available to embedded developers in a huge array of market segments of which Intel says it has identified at least 30. These segments will increasingly seek to select the right mix of compute density, speed, I/O, graphics performance, power consumption, size, thermal properties and more to fit the needs of their diverse applications. Just sorting through the array of choices that is becoming available is a task in itself, but one that many developers will probably welcome. Intel, Santa Clara, CA. (408) 765-8080. [www.intel.com].

CompactPCI in Control and Automation

High-Tech Control and Automation Apps—a Natural for CompactPCI Rugged, flexible CompactPCI meets extreme conditions, round-the-clock performance and high-speed processing requirements for traffic safety applications and industrial processing lines.

by David Pursley, Kontron

E

mbedded design for industrial control and automation markets is characterized today by a great need for flexibility within computing systems. Small, highly integrated rugged systems are the name of the game—and they frequently must include increased processing performance, low power consumption, high I/O bandwidth for data acquisition, scalable storage capability, reliability, long-life support and standards-based connectivity. These requirements are in turn being driven by new compute- and graphics-intensive human-machine interfaces and industrial automation applications that implement processes and controls for safe, efficient performance and connect the modern factory to the Internet. CompactPCI, with advantages such as ruggedness, rear I/O and an extensive range of PCI-compatible software, is recognized as a simple platform to implement, upgrade and maintain for these applications—even under the kinds of harsh environmental operating conditions typically found in factory, plant and transportation implementations.

FEBRUARY 2010 RTC MAGAZINE

Industrial control’s demand for flexible high-bandwidth network connectivity heralds a fundamental shift away from legacy industrial bus architectures and communications protocols, and movement toward more flexible standardsbased interconnect technologies—for example, communications protocols such as Gigabit Ethernet. CompactPCI is being used extensively in this arena, offering the benefits of high computing performance combined with its familiar software development platform and built-in ruggedness and reliability. With space-saving and powerful 3U and 6U form factors, CompactPCI provides designers with a small high-performance, cost-effective computing option that meets the availability, upgradability and maintainability requirements of many embedded industrial applications.

CompactPCI Automated and on the Move

Public transportation, for example, is seeing designers rely heavily on CompactPCI-based systems for control and automation processes. From a design perspective,

this market requires a significant range of systems and devices including train management and wayside systems, automatic piloting, interlocking and control center systems, as well as passenger information, onboard infotainment, tunnel safety and automated digital video surveillance. VBTC (Video-Based Traffic Control) Tunnel, developed by Austrian-based Center Communications Systems, is one such automated surveillance tool, promising to increase safety of tunnels used by road traffic while decreasing tunnel operating costs. Based on CompactPCI technology, VBTC Tunnel analyzes sequences of digital image data to recognize different categories and speeds of vehicles, distances between them, and safety-critical situations such as pedestrians in the tunnel, smoke, fog, cars driving on the wrong side of the road, freight dropped by vehicles, and breakdowns on the hard shoulder. VBTC’s new and improved algorithms are specially optimized for monitoring tunnels used by road traffic and demand both multicore performance and significantly higher bandwidth than previous systems. As a result, VBTC provides

Figure 1

an unprecedented level of automated precision, including an improved single-frame method and an intelligent alert management system, which independently interprets and filters the conditions automatically detected. For example, the system can recognize and filter out mud, mist or dust, all of which may have triggered unnecessary road alerts in previous systems as they were recognized as smoke, fire or lost cargo. Today’s VBTC only reports events that are relevant, reducing the amount of work required by the control center and all but eliminating unnecessary alerts. In the past, false alarms put control center personnel under pressure and risk, and also reduced the level of acceptance of the system itself. Using CompactPCI systems equipped with multicore CompactPCI boards, VBTC’s precision is rated exceptionally at 99.9 percent. In plain English, the system mistakes only one incident in a thousand that leads to an unnecessary alert. The likelihood that a particularly hazardous situation would fail to be recognized as such is a mere one in 100,000. These remarkable automated results are achieved by using up to eight analog cameras (superior to digital technology due to their greater sensitivity to light) installed in each of the tunnels to be monitored. Each is connected to CompactPCIbased Video Encoding Storage Analysis units via coaxial cable or optical waveguides. The video signal from each camera is recorded and the system stores the streams in a compressed form in a selfoverwriting mode for a defined period of time. If a hard drive ever happens to fail, none of the image data is lost, courtesy of both RAID-5 and RAID-10 technology

employed in various implementations. The units feature a CompactPCI system functioning as the main CPU, processing enormous amounts of data, analyzing video images in real time, and controlling the alert management system in sync (Figure 1).

Why CompactPCI

By incorporating 32nm processor technology along with multicore performance benefits, today’s CompactPCI boards are enabling more compute-intensive applications such as the VBTC example, as well as new prospects in terms of upgrading and extending the life of deployed systems. For instance, an existing tunnel surveillance system that uses 10 CompactPCI PICMG 2.16 single core CPU boards could conceivably reduce the number of boards to just two dual- or quad-core boards. Industrial designers seeking ultra high performance—both scalable and future-proof—may opt for multiple quadcore CompactPCI processor boards for these types of extremely data hungry applications.

CompactPCIbased solutions also benefit from an extensive range of PCIcompatible software—a significant benefit because PCI-based programming is familiar to most software designers. Combined with high bandwidth and reliability, designers tend to recognize this familiar computing model as an ideal solution for demanding data capture and processing applications. CompactPCI is also an inherently rugged and reliable system architecture. Pin-based connectors and locking handles enhance the ruggedness of CompactPCI. Gas-tight, high-density pins and socket connectors, as opposed to card-edge or slot-based connectors, mean PCI signal reflections are minimal based on low induction and controlled impedance. The gas-tight connectors provide a strong and reliable link between the board and the backplane. And with a large number of ground pins (220), designers are assured reliability by providing ample shielding and grounding for low ground bounce and operation in noisy environments. While card-edge and slot-based may both be suitable for non-mobile apps, the high-density pins in CompactPCI allow it to perform in more rugged environments, providing tolerance to the harsh extremes commonly found in non-stop industrial settings such as filling lines or traffic alert management RTC MAGAZINE FEBRUARY 2010

systems. CompactPCI’s ability to deliver rear I/O is another advantage, particularly coming from the smaller 3U form factor. rear I/O allows the system to have multiple communication interfaces, such as serial ports, Ethernet, or field buses, available on the backplane connectors (as compared to the front panel). This allows all board-to-board communication to be done without cabling via CompactPCI’s passive backplane. It also allows all external sys-

tions. Smaller controllers and platforms are in turn accelerating the trend toward industrial Ethernet for connecting smaller programmable logic controllers (PLCs) that traditionally used field bus protocols. Using Ethernet as a central communication system improves overall performance and interoperability by enabling devices from different manufacturers to communicate on the same network. An example of this type of design thinking comes from Krones, a world

tem connections to be made through that same backplane. With all I/O connections realized via the backplane, boards can be upgraded or replaced without touching cabling. This simplifies maintenance by removing the error-prone task of disconnecting and reconnecting cables after a component is replaced, thereby reducing the Mean Time To Repair (MTTR).

leader in supplying systems and complete processing lines for filling and packaging. Krones has developed highly flexible image processing systems based on the 3U CompactPCI platform (Figure 2). These sophisticated systems are indispensable to quality control on automated filling and packaging lines that demand high-speed image processing and zero failure tolerance. Reliable image processing is integral to quality control at numerous stages of the production and filling process, such as verifying container quality after cleansing, examining filling level and seal, checking the position of each label and “best before” date. And depending on

the number of stages required, a typical filling line could have as many as 20 different camera systems, each running different software applications. To accommodate complex processing lines in any number of industries, Krones developed a cost-effective system that was also easy to integrate, install and maintain regardless of its specific application area. Since automated systems must operate 24/7 under tough environmental conditions such as handling strong vibrations resulting from conveyor belts and other plant machinery, reliability is a critical factor in this design. Krones ultimately developed a universally applicable system incorporating a central server and distributed image processing units based on custom-designed CompactPCI boards (Figure 3). A rugged system, with robust connectors and secure fittings such as the metal guides and metal front plate holding the CPU boards firmly in place within the camera system’s mounting case, is ideal for the high-speed operation of most processing lines. Additional rugged performance and resistance to shock and vibration is achieved through the system’s fanless design with a heatsink screwed directly to the board along with direct soldered CPU and memory. CompactPCI connectors are inherently more robust due to their pinbased (versus card-edge or slot-based) design. They further the system’s ability to protect against damp conditions and aggressive airborne agents often found in filling plants. In the Krones inspection and control system, the central server is connected via Fast Ethernet to a number of distributed image processing systems positioned at various stages of the production line. Each image processing system consists of up to four digital cameras (the actual number depends on the specific application), the corresponding number of frame grabber cards and a customized Kontron CompactPCI CPU board. The cameras preprocess information, then uncompressed image data is transmitted by the frame grabbers to the CPU board. The data varies with the type of application, and could include a simple black and white bitmap, gray scale image or an RGB image. Sophisticated image processing software

CompactPCI Plus ®

written by Krones determines whether a container is clean, contaminated or filled to specified limits, depending on the system’s designated task. Results, including an evaluation of the product as acceptable or defective, are transmitted back to the frame grabber and forwarded via Ethernet to the central server. The central server is responsible for high-level control of the processing line, and all of this happens in very fast real-time operation. The CompactPCI board in the Krones system is optimized for cost savings. Since the board boots over the network from a central server, there is no need for a battery, clock buffer, CompactFlash or hard drive. Unnecessary interfaces are also omitted; each board contains only one Ethernet port for communicating with the central server and 4x CompactPCI slots for the frame grabber cards. Software was customized as well, with a specific BIOS enabled for Etherboot 3.6 compatibility. As a result, Krones is able to stock large quantities of cost-optimized boards, maintaining the right price-performance ratio and providing its customers with a rugged, reliable and price-sensitive solution. Image processing units with the same hardware configuration can be deployed on a wide range of different applications. They are like “blank slates,” applicationindependent and ready to perform whichever image processing task is required— creating a design concept that keeps production and maintenance costs to a minimum. For example, an image processing system used for reading labels can be quickly and cost-effectively unmounted and re-integrated into an earlier processing stage where it might perform a completely different image processing task. Systems are not configured for specific applications and are simply assembled with cameras, frame grabbers and CPCI board, allowing for efficient manufacturing with minimal integration costs regardless of whether they are used for measurement, surface inspection, texture inspection, code reading, text reading, print and inscription control or behavior analysis. Replacement systems are always on hand as well, since there is no need to supply an application-specific replacement. There is a lot to like in designing with standards-based CompactPCI for indus-

CompactPCI’s staying power is strong and growing, based on its ability to deliver high-processing capabilities and huge I/O throughput in a proven small and rugged form factor. Advancements in space and energy savings, coupled with additional advantages such as rear I/O and the extensive range of PCI-compatible software, mean designers are paying attention to CompactPCI and how they can use it to quickly achieve the right blend of performance, cost and forward-thinking required for next-generation designs.

CEO NETWORK SECURITY PANEL

Security for Networked Devices—

A Special CEO Panel THE QUESTION:

With embedded devices increasingly connected not only to local networks, but also via gateways to the Internet and ultimately to large servers, the issue of security spreads from the servers to even the smaller and resource-limited devices. Where do you see the major vulnerabilities for such diverse networks and what do you see as the effective strategies for securing them?

Dan O’Dowd

CEO, Green Hills Software The world’s commerce and critical infrastructure is increasingly dependent upon the security of embedded devices, their software content and their communications. Yet today’s security posture for most embedded systems is hopelessly inadequate. Devices are saddled with vulnerabilities in both operating systems and applications. We employ filters, scanners and Patch Tuesdays, but there are always new vulnerabilities that leave our critical resources exposed. Security-critical systems software (e.g. operating systems, hypervisors and communications stacks) and applications must provide users with a high confidence that the system will protect high-value information and services against sophisticated attackers while remaining cost-effective and easy to use. The techniques for achieving this are well known amongst an all-too-small population of the embedded developer community. For example, no commercial jetliner fatalities have occurred as a direct result of an avionics software flaw. High-assurance software developers follow a design and development process that is foreign to what most call “best practices.” In fact, “best practices” has become a euphemism for “whatever you can get away with.” For example, general-

purpose operating systems such as Windows, Solaris and VMware are rated EAL 4+ under the international Common Criteria security standard. The specifications for these ratings assert protection only against “inadvertent or casual attempts to breach the system security.” That is not secure by anyone’s definition. The most effective strategy for securing embedded systems and their connected networks and servers is to apply high-assurance methodology efficiently. We call this PHASE—principles of high-assurance software engineering. PHASE consists of: minimal implementation, componentization, least privilege, secure development process and independent expert validation. It is much harder to create simple elegant solutions to problems than complex, convoluted ones. Systems must be put together from small components, each of which is easily maintained by a single engineer. Components must be provided access only to those resources that are absolutely required. Security-critical components must meet the most rigorous development process standards, such as those found in DO-178B Level A. One example of the result of PHASE is Integrity, Green Hills Software’s operating system technology that is the


CEO NETWORK SECURITY PANEL

world’s first software to achieve a high-assurance Common Criteria security certification. In contrast to the EAL 4+ standard, our certification was at EAL 6+/High Robustness. This is the assurance level required to protect classified information and other high-value resources at risk of attack from hostile and well-funded attackers. This is secure by anyone’s definition. Among other things, EAL 6+ requires NSA penetration testing and formal methods to mathematically prove system security. We need to work together as a community to promulgate these higher standards and enable developers to raise the assurance bar in their own applications. Green Hills Software stands ready to help with software component building blocks, tools, training and consulting. The ramifications of failing to improve our embedded network posture are perhaps obvious, yet continue to be underestimated or ignored by stakeholders across industries. The recent example reported in the Wall Street Journal on December 17 stated, “Insurgents Hack U.S. Drones.” Unmanned aerial vehicles (UAVs), one of the more promising embedded networking applications in the aerospace world, have been hacked and their video feeds intercepted by insurgents in Iraq and Afghanistan. The developers and users of these UAVs were well aware of these vulnerabilities but underestimated the enemy’s ability to exploit them. This appalling lack of security is easily prevented by proper application of and dedication to the PHASE principles. As we look forward, we will continue to see dramatic increases in the big three C’s—Connectivity, Complexity and Cunning. Devices are increasingly connected to open networks; these devices are shipping with more and more software, leading to more vulnerabilities; and attackers are ever more sophisticated and determined. Following today’s “best practices” is simply not going to get the job done. A paradigm shift in device development is in the works, and the developers and organizations who embrace it will realize improved product reliability, increased market share, longer time in market, better product pricing power, reduced maintenance costs and, of course, bigger profits.

Joann Byres

CEO, Byres Security Anyone who uses a computer today is all too aware of the numerous security vulnerabilities occurring in commercial operating system and office software. However, most of us don’t realize that vulnerabilities are just as prevalent in hardware used for control in critical systems such as electrical power generation, oil and gas pipelines and water utilities. Most of these supervisory control and data acquisition (SCADA) system vulnerabilities are not well publicized, but in the course of our research we have seen many industrial devices that are so flawed they could be easily exploited by an unskilled hacker. For example, one Programmable Logic Controller (PLC) failed while being scanned with a standard security port scanning tool, indicating a serious TCP implementation issue. In another case we saw a PLC that could be completely taken over with a simple buffer-overflow attack against the appliJoann Byres, CEO, Byres Security. cation layer protocol it used Joann Byres’ business management for inter-device coordination. skills were developed when she owned Sometimes the vulnerand managed an industrial construction abilities are so serious that company for over twenty years.

SCADA engineers don’t want their system to be vulnerable to attacks, but most of these devices (and the protocols they use) were designed at a time when security was not a consideration in the SCADA world. Since the primary focus in any SCADA controller is,

22

FEBRUARY 2010 RTC MAGAZINE

quite reasonably, control functionality, security design has had to take a back seat over the years. Thus, most SCADA devices and protocols offer no authentication, integrity or confidentiality mechanisms, and can be completely controlled by any individual that can “ping” the device. Nor can they be easily patched or have security features added to them, even when security vulnerabilities are discovered. For example, adding even the most basic encryption technology to all the SCADA controllers in existence is a pipe dream. The existing CPUs do not have the horsepower to support encryption, and the replacement cycle for SCADA hardware is over 20 years. So, while some SCADA devices will be replaced, it is unlikely that all the control systems currently in use today will be able to natively support authentication before 2030. This leaves millions of legacy control systems open to attack from even the most inexperienced hacker. SCADA security is not achieved by blindly applying IT security solutions, since the goals of IT security differ from those of the process control world. The IT security manager sees data confidentiality as paramount (don’t let those credit card numbers be stolen), while the plant manager focuses first and foremost on human and plant safety. These differences in goals can translate into huge differences in acceptable security practice. For example, using standard password lockout procedures just isn’t acceptable for most operator stations in SCADA control rooms—the default state needs to provide access for the operator, not lockout, the opposite of the IT assumption. Imagine the impact if, during a reactor emergency, the operator panics and misspells his password three times, causing the console to lock out all access for the next 10 minutes. Password lockout is considered good policy for protecting IT servers, but it certainly isn’t going to work in the control room of the average industrial facility. A common industry response has been to rely on a single firewall to try to completely isolate SCADA systems from the outside world, assuming that all security problems arise from outside the SCADA system, and those that do make it in come through obvious pathways that can be managed by the firewall. Unfortunately, an analysis of 75 control-system security incidents between 2002 and 2007 showed that over half of the attacks came through secondary pathways such as dial-up connections, wireless systems and mobile devices. Many are human pathways such as contractors’ laptops, USB drives and inappropriate employee behavior. Others are communication systems that aren’t based on the typical local area network technologies—e.g., serial and telephone connections to remote process equipment, modems and wireless systems. Fortunately, the standards bodies responsible for SCADA security, such as the International Society of Automation (ISA) and the International Electrotechnical Committee (IEC), are suggesting a more effective solution. They point out that effective security is created by layering multiple security solutions, so that if one is bypassed, another will provide the defense. Based on this defense-in-depth concept, they mandate a “zone and conduit” security model. A SCADA facility is first divided into a number of different security zones,


CEO NETWORK SECURITY PANEL

based on the function, typical users and the potential consequences of failure. Next, security conduits are used to interconnect the zones, with industrialized firewalls or encryption devices managing the conduits. For example, in a refinery, a safety integrated system (SIS) might be in one zone, the process control system in second zone, the data historian in a third zone and the IT network in a fourth zone. Security breaches in each of these systems could result in different consequences, so it makes sense to handle each individually. For those devices like PLCs and SCADA controllers, where patching, anti-virus or security solutions arenâ&#x20AC;&#x2122;t available, the use of low-cost industrial security appliances directly in front of each control device (or group of devices) needing protection is gaining popularity. For example, aviation giant Boeing is currently deploying â&#x20AC;&#x153;SCADA endboxesâ&#x20AC;? in their 777 manufacturing plant as a first stage in a worldwide rollout of a secure automation solution. These industrial security appliances act as security proxies for the SCADA devices, delivering security services (such as encrypted tunnels) to the SCADA controllers, while being able to take advantage of the security infrastructures offered by the IT department such as PKI certificate deployment and Metadata Access Protocol (MAP) policy servers. Without the SCADA

endboxes to offer the â&#x20AC;&#x153;translationâ&#x20AC;? of services, the PLCs simply could not be part of the Boeing security infrastructure. Going forward, more sophisticated protocols and architectures will be needed to manage these widely distributed security solutions. Protocols such as HTTPS, syslog and SNMP work well for deployments that include dozens of security appliances, but break down when the numbers climb into the hundreds or thousands. And things get even messier when the sources of data needed to make policy decisions can come from a large number of distributed real-time sources such as badge card readers and position location monitors. Boeing is basing their SCADA policy coordination on technologies such as Metadata Access Protocol (MAP), which offer promise in the ability to collect and coordinate large amounts of security information. Ultimately, the embedded devices used in SCADA systems will be able to be secure on their own. But that day is still many years off, and until then, the use of SCADA endbox-type security solutions will be needed to fill the gap and protect our critical infrastructures.

CEO NETWORK SECURITY PANEL

Adrian Turner CEO of Mocana

With millions of new electronic devices connecting to the Internet every day, and the rise of the “internet of things,” we are now encountering a third wave of hacking—one that encompasses not only traditional computers and networks, but also intelligent devices: wireless phones, routers and switches, printers, supervisory control and data acquisition (SCADA) systems, and even medical devices and the utility infrastructure. This new hacking wave is already bypassing the “street-cred” phase and moving directly toward well-honed, sophisticated and for-profit (or formayhem) attacks. At Mocana, we see four interesting security trends emerging for the internet-of-things:

Since security for personal computers is getting stronger, hackers are increasingly looking for “softer” targets. In their sights are the millions of industrial control and coordination, or SCADA, devices. SCADA devices monitor and control power generators, refineries, water treatment facilities, oil pipelines and electrical power systems. They also comprise an essential component of our industrial, technology and communications infrastructure, controlling building security, manufacturing plants, airport traffic and military vessels. Installed SCADA devices are sometimes decades old and operate with legacy computer hardware. They tend to be configured with off-the-shelf networking software and have weak internal security protections.

Although guarded by a hard shell on the outside, with locks, gates and security personnel, industrial facilities may still contain a soft center—their computerized control systems—an easily penetrable core that now is exposed to the outside world through the Internet. In the past, the majority of SCADA attacks were perpetrated by insiders who had access to the controls: disgruntled ex-employees or saboteurs. Now, experts are seeing more and more attacks originating from external sources, even from residents of foreign countries. In 2004, a British Columbia Institute of Technology (BCIT) analysis of 24 control system security incidents instigated by outsiders showed that 36 percent came in through the Internet. One of the problems with assessing the prevalence of SCADA attacks is that they are rarely reported in any detail, for fear of encouraging further attacks and compromising national security. The incidents are far more widespread than commonly believed, the targets more wide-ranging, and the attackers are not who we think they are. Even more ominous, the data shows that getting into most control systems is surprisingly easy. For example, in 2008, a teenager in Poland rigged a TV remote control to control the switch tracks of trams. There were four derailments and twelve resultant injuries. Most frighteningly, attacks against SCADA devices are being carried out by enemy nations as part of a greater “cyberwarfare” strategy to sabotage the U.S. economy and infrastructure. At a conference in January 2008, a senior CIA analyst shocked his audience by revealing that cyberextortionists in another country had already caused a power outage affecting multiple cities. Finally, it is important to note that our infrastructure is actually moving away from systems that are traditionally labeled as “SCADA.” For instance, few know that some of the world’s largest botnets—that infamous army of zombified computers programmed to follow a hacker’s bidding—aren’t made up of PCs, but of wireless access points running Linux!

Trend #2: Manifestation of Long-Predicted Threats to Cell Phones & Smart Phones

With the rise of unlimited data plans, open networks, readily downloadable applications, and the lack of strong security—hackers, spammers and phishers are now beginning to recognize the profit potential of mobile phones. Adding to the allure of mobile hacking for cybercriminals are the fraud opportunities presented by the burgeoning mobile financial services market. The hottest mobile phones are also, unfortunately, the most vulnerable to attack. The newest of the 420 smart phone viruses analyzed have in 5 years reached a state of sophistication it took computer (PC) viruses almost two decades to achieve. Several features of smart phones make them particularly tempting targets. For one, mobile users tend to be less guarded


CEO NETWORK SECURITY PANEL

than computer users about clicking on links, enabling SMS phishers (“SMishers”) to gain information or send malware via a link in a legitimate-looking text message. In addition, mobile phones are a treasure trove of personal information, such as phone numbers and addresses, which criminals can extract and sell in the ID fraud marketplace. And, to make things even easier for cybercrooks, location-enabled smart phones let spammers personalize malware for each user by mentioning their locale; for example, by prompting them to click on information about a disaster that supposedly occurred in their area. The most worrisome trend in mobile hacking is the specter of a mobile botnet. Some smart phones already have more memory and higher processing power than laptops from just a few years ago. A constantly moving and adapting mobile botnet presents a compelling business proposition for hackers and an interesting real-world case study in chaos theory.

Trend #3: Attacks on Mission-Critical Military Systems with Cheap Off-the-Shelf Tools

The Wall Street Journal recently reported that militants in Iraq used $26 off-the-shelf software to hack into live video feeds from U.S. Predator drones, providing them with information they might use to evade or monitor U.S. military operations. Shiite fighters in Iraq used cheap commercial software like “SkyGrabber” to routinely capture drone video feeds. The vulnerability lies in an unencrypted downlink between the drone and ground control. The U.S. government has known about the flaw since Bosnia in the 1990s, but the Pentagon assumed local adversaries wouldn’t know how to exploit it, the officials said. The incident puts the issues surrounding device security into sharp relief. Embedded engineers avoid integrating robust security measures into these systems because it’s often perceived as “not worth the effort.” Securing embedded systems is seen as difficult, and there’s a strong perception that these systems aren’t really being threatened. Both perceptions are incorrect. Recently the U.S. military found substantial proof that the feeds were being intercepted and shared with extremist groups. Now senior military and intelligence officials say the U.S. is “working” to encrypt all of its drone video feeds from Iraq, Afghanistan and Pakistan, but there is no word on when the initiative will be finished. By waiting until after the system was fielded, instead of designing security in at the beginning, the military has made securing the system much more expensive and difficult than it had to be. And this is a story that we’ll see repeated across all embedded systems in all industry segments. Adding encryption to a proprietary network system approaching 15 years old involves more than placing a new piece of equipment on individual drones. Instead, many components of the network

linking the drones to their operators in the U.S., Afghanistan or Pakistan need to be upgraded. Still, the Air Force is buying hundreds of new model Reaper drones, whose video feeds can be intercepted in the same way as with the Predators. A Reaper costs between $10 million and $12 million each—and General Atomics, the manufacturer, expects the Air Force to buy as many as 375 Reapers.

Trend #4: The Rush to Network Medical Devices Outpaces Security

One truly scary attack trend is the growing offensive against medical devices—a graphic illustration of the point that compromises of embedded devices are often more likely than PC hacks to have real-world consequences. The bar for embedded security needs to be higher, not lower, than for PCs, but that’s rarely the case right now. A large number of medical devices, such as heart pacemakers, implantable cardioverterdefibrillators (ICDs), bedside monitors, MRI machines and portable drug-delivery pumps, have a CPU and an IP address that enable them to transmit and receive information, but also expose them to attacks. For example, over 300 hospital devices including MRI systems were recently successfully attacked by the Conficker worm. Medical devices far outnumber PC workstations in hospitals, and they’re usually the softest targets on a hospital network, lacking firewalls, malware protection, strong encryption, or even recent security or OS updates. Medical devices are increasingly leveraging IP and common OS platforms that enable them to utilize large libraries of software and communicate more easily. But in the rush to establish common platforms and network these devices, security concerns have been poorly addressed. The same types of attacks that have traditionally targeted sectors such as consumer electronics are being directed at medical devices, with potentially fatal consequences. Attacks we’re beginning to see directed at medical devices include sniffing, data theft & destruction, zombification and bricking. In a paper published last year by the Medical Device Security center about pacemakers and ICDs, researchers described how they were able to hack into an ICD and intercept private data transmissions. They revealed that ICDs could be hacked to alter patient data or reset how shocks are administered. Tadayoshi Kohno, a lead researcher on the project at the University of Washington who has studied vulnerability to hacking of networked computers and voting machines, says that “the risks to patients now are very low, but I worry that they could increase in the future.” Mocana, San Francisco, CA.

Greg Nocoloso CEO, Eurotech

Currently, there is still a large percentage of manufacturers within the “embedded” appliance product sector who are relying on the notion of “security by obscurity” strategy for TCP/IP network security. As both wired and wireless network connectivity become a requirement for even the smallest embedded computer node, product designers must start looking at how to secure these devices for continuous operations in a “hostile” network environment.

There are several layers of technology that can be examined here with regard to where device security needs to be addressed. This includes hardware design, BIOS/bootloader, operating system implementations and application framework design. At the most basic level, hardware designers need to consider the implications of hardware-level security. This includes hardware-based security “firmware” devices such as trusted platform modules (TPMs) and tamper detect hardware features. Many sectors including banking and gaming require both the physical

26

FEBRUARY 2010 RTC MAGAZINE

level of security offered by tamper detect circuitry as well as the initial core “root of trust” offered by the functionality of trusted platform modules. A final consideration of the hardware design must offer the option of write disabling the bootloader or BIOS device in final production such that initial core root of trust can be established. At a firmware level, overall device security must start with the bootloader/BIOS firmware. As noted above, most secure device specifications dictate (from both a physical and programmatic standpoint) that the device can power up and determine that neither the bootloader/BIOS nor operating system binary images have been changed or tampered with. In most cases this is accomplished through the use of a TPM in conjunction with the boot firmware. TPM technology offers a hardware “vault” that can encrypt and contain hash keys of both the booting firmware as well as the selected operating system image. The booting firmware must then validate both itself as well as the operating system image using the TPM hardware. This validation process establishes the core “root of trust” so that the device can then continue the boot process into the operating system knowing that no malicious changes have occurred on either the boot media or the operating system. At this point the hardware design can be considered a “secure platform” in a raw sense of the word, and we can proceed to the next level of examining operating system selection. If we follow along in this process, the security of the platform is handed off from the boot media to the operating system. Most available OSs provide the capability to add a layer of “security-enhanced” operations. We won’t go into a great level of detail here, but suffice it to say that Windows, Linux and other popular RTOSs provide the APIs required to continue the security policies established by the TPM, and have “access control security policies” for secure user and application access to the system resources (file system, network access, device access, etc.). Up to this point we have considered the security aspects from the perspective of physical and internal security, but now with the operating systems up and running, we can turn our attention to the various communications interfaces and how to address their security requirements. Most embedded compute platforms still provide a local console (RS-232, USB, etc.). Of course, local console security still needs to be managed by the configuration and set up of the system with additional attention to user access control. The primary consideration here is the use of TCP/IP networking interfaces given the critical role of many of these types of embedded compute platforms. Ethernet, Cellular, WiFi, Bluetooth and RS-232 (via PPP) can all have connections into the TCP/IP stack of an embedded platform and can all present security risks. At a basic level it is critical to have an up-to-date TCP/IP stack implementation. Most of the modern embedded OSs do


CEO NETWORK SECURITY PANEL

supply this level of conformance to the latest TCP/IP standards and the associated RFCs that specify the operations. Software engineers porting the OSs must have a good understanding of all levels of TCP networking implementation since risks can even exist at the lowest level of the stack implementations. ICMP, TCP and IP layers of the stack all need to be considered when porting an OS and again in context to the manner in which the system is configured. TCP/IP utilities within the OS itself, such as routing, address translation, open ports and security, must all be considered and set up as the default to be secure and not allow access without authorization and authentication. These would all be considerations within the initial setup of a system. On top of these concerns, the final level of consideration is the end application. Overall device security is only as good as the final application running on it. At the lower levels this does include the APIs to the operating systems with regard to existing security features and default configuration. But the application has the ability to open ports, allow access, configure routes, etc., within the overall scope of the system. Even following all of the TCG recommendations at a platform level does not guarantee security if the appli-

cation developer is not well versed in TCP/IP networking technology. One excellent source of information for an overall platform security specification is offered by the Trusted Computer Group (TCG) (http://www.trustedcomputinggroup.org/). This specification covers the lifecycle of an entire “secure compute” platform. Eurotech, Columbia, MD. (301) 490-4007. [www.eurotech.com].

leads to cost savings; electric Independent System Operators (ISOs) need real-time generation output for managing shortages, and selling excess. Business must be agile; just in time manufacturing enables quick response to volatile supply and demand. Maintenance costs can be minimized by enabling remote debugging and repair; integrating SCADA and IP networks eliminates the expense of additional cabling in an industrial environment, which can cost up to $3000 per foot. Even efforts to protect the networks can lead to unintended consequences. Regulations such as the Critical Infrastructure Protection (CIP) standards from the North American Electric Reliability Corporation (NERC) drive integration, as electric ISOs seek access to production data in real-time to demonstrate compliance. Ironically, the pursuit of security itself can lead to exposure! Protective measures such as centralizing access control to minimize tampering, or extending closed-circuit TV monitoring or VoIP to remote stations, require increased accessibility.

Challenges of Interconnectivity

Clearly, interconnectivity is the wave of the future – but many control system components were conceived in the past. Control devices, and the PCs that manage them, are very vulnerable – not only to malicious attacks using malformed network data, but also in many cases to even high levels of well-formed network traffic. PLCs and remote terminal units (RTUs) are typically optimized for highperformance real-time I/O, not for robust network interfaces. In addition, control networks run continuously for weeks or months at a time, and many systems cannot be shut down even for a few minutes without significant financial or safety impact. As a result, the PCs in these networks are often not up to date with security patches or anti-virus definitions. Secondly, control networks are usually

poorly segmented, with little or no separation between different subsystems or even different physical locations. If a problem occurs in one area of the network, it will spread rapidly to other unrelated systems elsewhere in the network. Poor segmentation also makes it very difficult to locate the origin of a problem and resolve it at the source. In the early days, control net-

works started as very simple ‘islands’ of automation, but they have steadily grown in size and complexity over time. The third common issue is the existence of multiple points of entry into these networks. Many control network managers will swear up and down that their control systems are not connected to the enterprise network or the internet, but authorized penetration testing often shows otherwise. In addition, there are often other transient paths of entry that don’t even show up on a network diagram: VPN connections, laptops or even USB memory sticks traveling in and out of the plant can easily carry viruses right into the heart of the plant network. Theoretical vulnerabilities lead to real-world incidents with far-reaching consequences including loss of productivity, revenue, and even loss of life. A Zotob worm infestation caused the shutdown of 13 assembly lines, affecting 50,000 work-

to a pipeline rupture and subsequent fire that killed three young men in Bellingham, WA. Most IT managers have significant experience addressing cyber security issues in enterprise networks, so why can’t managers of control and SCADA networks simply apply the same technologies in their systems? Control systems have unique requirements that until recently have not been addressed by available security solutions. These requirements include harsh physical and electrical environments and support for the unique communication protocols that are common in industrial networks. Such systems also require the ability to install, configure and test these security solutions in a ‘live’ operating network without putting the plant at risk.

plement secure connections between their enterprise network and the manufacturing plant. Because of the size of the product being built, the manufacturing tooling - mounted on mobile crawlers - roams throughout the entire facility. Essentially, the product being manufactured remains stationary while the production line moves around the product, the reverse of most production sites. Due to the mobility requirement, the crawler must use wireless connectivity with its potential security challenges, to connect to the network. Open standards from the Trusted Network Connect (TNC) of the Trusted Computing Group (TCG) enable a solu-

network connections to the crawler over the wireless network. When initially deployed, the appliances first check in with the MAP to collect their corporate security certificates. Next, they retrieve their security policy (firewall rules and VPN security associations) via the same server. And if unauthorized network traffic is blocked by the firewall on a crawler, the Tofino can report this information to the MAP in real time. IF-MAP, an open protocol with support from diverse vendors, could then be used to respond in a variety of ways, including alerting the network security team, logging the incident in a database, or even changing security policy

tion that combines products from multiple vendors, all interoperating via standard interfaces. The cornerstone of this system is the MAP, or Metadata Access Point, which acts as a ‘clearing house’ for a wide variety of transitory data. A key element in the operation of the TNC-based security solution, the MAP provides flexibility and interoperability that simply cannot be achieved with proprietary solutions.

if appropriate. MAP-based functionality can go far beyond the crawler’s security appliance and other network-based security products. A wide variety of MAP-capable devices enable the company to implement highly optimized security solutions, customized to their specific needs (Figure 1). As each crawler moves around the plant, MAP-aware wireless access points report each crawler’s location to the MAP; the crawler’s security policy can be configured based on the physical location of the crawler. For example, if the crawler is located in a service bay, firewall policy allows a PLC engineering workstation to upload new firmware or logic program-

ming into the controller. Such activity is prohibited when the crawler is in use on the plant floor. Other systems that interface to MAP, such as physical plant security products, can be configured to interoperate in ways that would be impractical, if not impossible, using proprietary solutions.

SCADA - One Type of Control Systems Network

As shown in Figure 2, the presence of a centralized controlling element differentiates a SCADA – Supervisory Control and Data Acquisition – network, as opposed to other control systems where multiple components might make individual control decisions. A SCADA network generally includes a control center and will usually have a backup control center to ensure availability and disaster recovery. Operators interact with the system via a Human Machine Interface (HMI). The control center has a main terminal unit (MTU) that connects to one or more remote terminal units (RTUs)– which could be PCs or embedded OSs. The RTU communicates with an intelligent electronic device (IED) – this might be a microcontroller or a programmable logic controller (PLC) which runs the logic for running, controlling and monitoring a machine or robot. These components have a range of connectivity – anything from modems to wireless to microwave to the Internet. They communicate with each other across a suite of protocols including DNP3, a distributed network protocol; ICCP, an intercontrol-center communications protocol; Modbus, a protocol that originated on serial links but has since been ported to IP; or OPC, an open connectivity protocol originally based on Microsoft object linking and embedding (OLE) and distributed component object model (DCOM).

Open Standards for Network Security

Trusted Network Connect (TNC) is a work group of the Trusted Computing Group (TCG), an industry standards organization focused on strong security through trusted computing. TNC is completely vendor-neutral; the full set of TNC specifications is freely available for any-


technology connected

one to implement, and TNC-based products have been shipping for almost five years. TNC standards provide an architecture and open interfaces that allow interrogation of an endpoint to determine its integrity and compliance with security policies. When an endpoint requests access to the network, a policy server queries the endpoint, determines user identity and endpoint health, and makes an access control decision based on the resulting information. The policy server sends a policy decision to an enforcement point, telling it whether to permit access, deny access, or quarantine the endpoint. TNC interfaces standardize communication between these components at the network, transport, and application layers (Figure 3). TNC’s IF-MAP standard extends the TNC architecture to allow data sharing across a huge variety of security and networking systems. The Metadata Access Point, or MAP, is a central clearinghouse for endpoint metadata; MAP clients can publish, search for, and subscribe to notifications about that metadata. Any networking and security technology can be a MAP client; examples include intrusion prevention system (IPS) platforms, vulnerability scanners, dynamic host configuration protocol (DHCP) servers, physical security systems such as badge access solutions, and even application servers. These components can act as sensors adding data to the MAP and/or act upon information received from other components. Now, more than ever, organizations interconnecting control system networks with corporate IT networks need to be aware of potential risks. Planning, processes, and technology are required to adequately reduce exposure, mitigate the risks associated with a hyper-connected environment, and prepare the infrastructure to securely handle change. The current trend toward higher levels of integration between enterprise and control/SCADA networks will continue to accelerate as operators seek improved productivity and return on investment (ROI). However, this ROI will not be realized without significant improvements in control system security. TNC and MAP provide an open eco-

system of interfaces, tools, and products that enable robust and flexible security architectures to be deployed quickly and cost-effectively. Moreover, integration of specialized security products demonstrates that open standards from TNC enable management of security policy for both the enterprise and control networks from a single set of tools, offering high levels of security in a very cost-effective solution.

and therefore static energy is proportional to time. At lower frequency, execution time increases and so does static energy. Furthermore, the power used by RAM is independent of CPU core voltage. It also comprises both a static component, and a dynamic component roughly proportional to the number of memory accesses (loads and stores) by the CPU, which depend on the core frequency. However, memory accesses are slower than CPU operations, and the CPU frequently stalls waiting for data from memory. When the CPU runs slower, the number of stall cycles (which result in waste of dynamic CPU energy) is reduced. Thus, the relationship between energy consumption and core frequency is a complex function of hardware characteristics and program behavior. While energy use by CPU-bound programs (which rarely access memory) tends to be minimized at high clock rates, for memory-bound programs, minimal energy consumption occurs at low frequencies. DVFS is today a standard feature of most microprocessor families, but has yielded mixed results from software sys-

tems that attempt to drive it, due to the above complexities. While OS kernels and individual device drivers can readily address DVFS control registers, divergent approaches and heuristics exist for scaling and many factors can influence return on DVFS investment: • Relative CPU and memory power consumption • Importance of static vs. dynamic power use by CPU, memory and other components • Degree of memory-boundedness of applications • Complex trade-offs between DVFS operating points and sleep modes

Voltage (VDC)

Multi-processing on multicore silicon, once a high-end capability, is today mostly mainstream. Silicon suppliers routinely integrate specialized companion processors alongside applications CPUs on a single substrate (asymmetric multiprocessing or AMP), and are also deploying 2x, 4x and other parallel configurations of the same ARM, MIPS, Power or x86 architecture cores (symmetric multiprocessing or SMP). Driving this evolution are needs for dedicated silicon to process multimedia, graphics, baseband, etc., the need to sustain growth of compute capability without power-hungry high frequency clocks, and requirements to run multiple OSs on a single device. While multicore, multi-processed systems may limit power consumption in some areas, they present steep challenges to energy management paradigms optimized for single chip systems. In particular, multicore limits the scope and capability of DVFS because most SoC subsystems share clocks and power supplies. One consequence is that scaling the operating voltage of one of several SoC subsystems (when even possible) can limit its ability to use local buses to communicate with other subsystems, and to access shared memory (including its own DRAM). Clock frequency scaling of a single SoC subsystem also presents interoperability challenges, especially for synchronous buses. And, since multicore systems in SMP configuration usually share Vcc, clock, cache and other resources, that requires that DVFS

apply to all constituent cores and not to a useful subset. Silicon supplier roadmaps point to further multiplying numbers of cores—today 2x on embedded CPUs, and soon 4x, 8x and beyond. This surfeit of available silicon will encourage designers to dedicate one or more cores to particular subsystems or functionalities (CPU-function affinity). Some dedicated operations, like media processing, will use cores in a binary fashion – at full throttle or not at all. However, most other functions will impose varying loads, ranging from a share of a single core to saturating multiple cores. All-or-nothing use is fairly easy to manage, but dynamic loads on multiple cores present much greater EM challenges.

Multiple OSs and Energy Management

Most OSs are mediocre resource managers. If OSs were competent in resource management, virtualization in the data center would not enjoy the missioncritical role it does today. Embedded OSs aren’t any better at managing resources than their server counterparts. They assume static provisioning and full resource availability with simplistic state models for resources under their purview. Many intelligent devices also deploy multiple OSs: high-level OSs like Android, Linux, Symbian, WindowsCE or WindowsMobile to provide user services and to run end-user applications, and one RTC MAGAZINE FEBRUARY 2010

A good example lies in the Motorola Evoke handset. Devices like the Evoke and other current-generation handsets consolidate the diverse functions of a smartphone onto a single processor with one or two cores. Next-generation devices will build on silicon with even greater numbers of available cores, and will surely find ways for each subsystem to consume available compute capacity. In these devices, one subsystem would be the baseband modem, whose real-time software stack would comprise a load that fully occupies one or more full cores during peak processing (e.g., for streaming or voice conferencing), but typically consumes perhaps a fifth of a single core’s capacity when quiescent. Another subsystem would be an HD multimedia stack, requiring an additional core (or more) at full load, and zero when no media is displayed. A GUI stack might use a half core during heavy user interaction, and zero when quiescent. User applications would consume any remaining compute capacity when executing, and would occupy either zero cores when quiescent, or represent some other finite load with background processing (Figure 1).

or more RTOSs to handle low-level chores like wireless baseband and signal processing. These OSs and the programs they host may run on dedicated silicon, may occupy dedicated cores on a multicore system, or can also run in dedicated partitions of memory and cycles of a single shared CPU. High-level application OSs typically include their own EM schemes that leverage DFVS (e.g., Linux apm and dpm, and Windows/BIOS ACPI). Most RTOSs eschew any operations that curtail realtime responsiveness, leaving OEMs and integrators to roll their own or do without. Some do offer explicit power management APIs (e.g, vxLib vxPowerDown()), but usually lack coherent mechanisms for policy. Whatever the inherent EM capability of resident OSs, there remains the challenge of coordinating efforts in a multiOS environment. Even if one among sev-

eral OSs is capable of managing energy in its own domain, it will have no awareness of the EM capabilities and state of its peer OSs in the same system, adding to development and integration headaches. Even if all co-resident application OSs and RTOSs have some EM capacity, however rudimentary, how can system developers and integrators coordinate and optimize operation and energy management policy across OS domains?

A Real-world Example – Mobile Handset Energy Management

Legacy smartphones typically employ dedicated, separate CPUs for application processing, multimedia and graphics and for real-time wireless baseband modem operations. As multicore CPUs and virtualization become more ubiquitous, designs are migrating these separate operations onto partitioned single- and multicore processors.

Clearly, each of the functional stacks and the OSes that host them present unique challenges to managing energy with DVFS. In combination on a multicore CPU, it becomes nearly impossible to determine useful DVFS operation points and policy for transition among them, both on a per function basis and a coordinated one. The above scenario clearly illustrates that localized DVFS schemes are inadequate to address the needs of next-generation multi-stack multicore designs. Further analysis of the scenario also highlights the limitations of the coarse-grained assignment of functions to available CPU cores: • Peak loads for different subsystems can consume most or all of one or more cores’ compute capacity • Gross assignment/dedication of functions to cores can waste available compute capacity and potentially starve functions at peak load • Real-world total load is unpredict-


tech in systems

able due to third-party applications (e.g., with Android Market), and additional demands placed on communications and multimedia stacks from those applications and the traffic they generate • Scalable loads dictate sharing of available CPU cores across functions • Most silicon cannot run stably at all frequencies and voltages. Realworld energy management paradigms build on discrete, stable pairings of voltage and frequency (operating points)

Virtualization for Energy Management

Rather than try to salvage legacy EM paradigms from each functional domain, let’s employ the approach favored by data center IT managers – using virtualization for energy management. DVFS wrings incremental gains in energy efficiency by reducing voltage and clock frequency. A given CPU offers developers and integrators a set of safe “operating points” with fixed voltages and frequencies. As load/demand increases or decreases, EM middleware or EM-aware OSes transition from operating point to operating point (Figure 2). A logical extension of applying DVFS is reduction of voltage to 0 VDC and completely stopping the CPU clock. That is, utilizing only two operating points – Full Stop and Full Throttle – but employing them across the range of available cores: OP1 uses one core, OP2 uses two, etc. In multicore systems without virtualization, or with simple partitioning, wholesale shutdown of CPU cores presents additional challenges, because loads (OSes and applications threads) are tightly bound to one or more cores (complete CPU affinity, as in Figure 3). Shutting down a CPU core requires a policy decision between a shallow sleep mode—with fast entry and exit, but significant remaining leakage power— and a deep sleep mode—with low leakage power but high overhead at both entry and exit. Also, migrating loads across CPUs is nearly impossible; only loads already running as SMP can shed CPUs. Introducing virtualization neatly addresses the challenges of CPU shutdown

and CPU core affinity. First, instead of binding loads to actual CPUs, the presence of a full-featured Type I Hypervisor associates functional subsystems with dedicated virtual CPUs. Based on real compute needs and on policy established at integration time, the hypervisor can bind virtual CPUs to one or more physical CPUs (Figure 4.) and/or can share available physical CPUs among virtual CPUs as needed as suggested in Figure 1. To facilitate energy conservation, a hypervisor enables Full Stop of underutilized CPU cores by (re)mapping virtual CPUs and their loads onto fewer physical CPUs (Figure 5.). This neat trick is only possible through via the construct of virtual CPUs, which facilitate arbitrary mapping of loads to physical silicon and migrating running loads transparently across CPU cores. The resulting consolidation means that on average, more CPUs are in an off state and they remain there for longer, allowing more efficient use of deep sleep states. Shutting down whole cores leads to linear, and therefore highly-predictable, performance/energy tradeoffs, unlike DVFS, and is therefore easier to manage. DVFS can still be employed on the active cores for fine-tuning the energyperformance tradeoff. Since energy management is now handled by the hypervisor, with full knowledge of performance requirements, hardware-imposed constraints such as common core voltage are readily incorporated.

As mentioned earlier, embedded OSes are notoriously poor at resource management. Those with native energy management schemes have “been taught” to monitor their own loads and make energy management policy transitions. They are not, however, equipped to manage energy and CPU utilization outside their own purview, on other CPU cores running different OSes and accompanying loads. For multiple, diverse hosted OSes in a multicore system, effective energy management must “step outside” of the local context of functional subsystems (baseband, GUI, etc.) to a global scope that encompasses these subsystem together. The foregoing has been a brief review of energy management mechanism, and challenges presented to EM schemes by modern multicore systems. Of available software-based energy management mechanisms, only virtualization is positioned (in the global architecture/stack) to manage energy for all cores and all functional subsystems in concert. Since it is the hypervisor that actually dispatches threads to run on physical silicon, it is uniquely and ideally situated comprehend actual CPU loading (not calculated guest OS loads), and to scale power utilization and energy by bringing available cores in and out of service.

Customizing the operating system to work with the hardware and save power without adversely affecting operation is one of the most important and complicated steps of embedded systems design. Designers start with an out-of-thebox operating system, such as Windows CE or Linux, and implement additional capabilities to enable functionality specific to the board design. Optimizing the operating system (OS) is a large part of the system design process, and arguably the most time-consuming. Some board vendors deliver a board support package that requires the customer to create the operating system themselves. Since optimizing the operating system is one of the most labor- and time-intensive

and every power state in between, to make sure there are no failures. Laptop computers offer an excellent example of what happens when the operating system does not communicate properly with the hardware. A common operating system bug reveals itself when you “wake up” a laptop and it can no longer access a peripheral. The hardware certainly has the capability to enter and exit low-power mode, but the operating system failed to communicate correctly to the peripheral during powerup. OEMs and end users demand higher reliability and error-free operation from embedded systems—so extensive testing and validation ensures the system will function properly when the user puts it into a low-power state, and when they

power it back up. In addition to maximizing the hardware’s low-power states, the OS determines when there is an application running and tells the peripherals to wake up and start performing, or to remain in one of many sleep modes. Just about every part of the system has interfaces and on/ off switches, and the operating system must be customized to determine when power needs to be increased or decreased to each component. When the operating system detects that an application is using resources, it will increase the power supply and move the hardware and peripherals into an appropriate power mode.

Peripherals and Applications Designed for Low Power

After choosing and optimizing the hardware and operating system, you can select peripherals that will reduce power consumption. Good designers consider every last detail to save power. Some peripherals have communication protocols to allow you to put them into a low-power mode, or you can design the system with that function. Either way, select peripherals that support low-power modes and power off. Your operating system will dictate some of these peripheral choices since they are not all compatible with all operating systems. If the power saving functionality is not fully accessible, control command sequences can be extensive and complex. Ethernet is one example of a peripheral with sophisticated power management—it never goes to sleep, but if you choose the right components there are many ways to reduce power with a command control protocol. For instance, Ethernet can be programmed to remain in low-power state until an incoming message is detected, allowing it to wake and pass the data to the OS. For example, devices like the Intel 82574 Ethernet Controller can be configured to wake the board from a low-power sleep state. Another example of how peripheral choices can save power is the display. If a device is going to be used outside in daylight, a display with some reflective properties will reduce the need for backlight,


tech in systems

which can be a significant power savings. Identifying use cases to support powering off the display during non-critical periods is also very useful, making it important to select an LCD with the ability to support this level of control. After choosing peripherals that offer low-power states, the designer must spend a fair amount of time and complexity in the development cycle to make use of those states. Some embedded computer providers choose low-power peripherals, but don’t take advantage of the low-power capabilities in their development process. In the end, they are not able to reach the lowest power levels for the computer system as a whole, even though the individual specifications for each component promise power efficiency. At the detailed design level, you have to consider undesired circuit paths and insert the hooks necessary to use the available power-down features. These hooks will likely require additional I/O and partitioning power supplies to make sure the circuits that are powered down are really off. Most hardware power saving features must be controlled by driver software to make the features available to the application environment. This arrangement also allows for complete validation at the platform level prior to application integration, which is an important consideration that speeds integration and reduces field trouble reports. The application layer is another important factor in the power management equation, since the application is aware of which peripherals are connected and how to best handle them. Some integrated circuits can enter low-power mode based on their operating conditions on their own, but in most cases you will have to access the application layer to command the power reduction modes. A running application instructs the operating system to turn different functions on or off. For instance, a computer may turn off the display when the user is in motion, or power down the cellular modem when the 801.11 interface has connectivity. Since the application layer is typically handled by Eurotech’s customers after we

Reinventing Wireless Building Automation for Smaller/Retrofit Jobs The centralized approach to building automation systems limits small-scale, retrofit and limits local deployments because of the large overhead. A new decentralized/ embedded approach to automation topology and multiprotocol integration can deliver wireless automation’s economic benefits to this underserved market. by Simon Leblond and Hami Chanon, SCL Elements

building automation system can save money by lowering labor, power and other costs. It can also enhance occupants’ enjoyment of the space through optimized climate control, a more secure environment, etc. This translates into potential economic benefits of higher rents and/or a lower vacancy rate. When asked why a building automation system has not been installed, an owner will typically point to one obstacle: cost. This cost typically stems from three sources: hardware, installation and integration. The price of hardware has fallen in recent years, so specialized labor generally accounts for the largest share of deployment cost. New wireless technologies offer breakthrough savings on installation and maintenance, but bring their own troubles. In particular, new protocol support demands integration and human intervention for interoperability between devices and networks. Current solutions to protocol integration, such as Tridium’s Niagara AX or Schneider’s TAC Vista, rely on a central, shared platform in the form of a dedicated server or networking device. This approach works best for large implementations that can justify up-front costs of setup, software licensing and dedicated hardware. It leaves an underserved market of properties that require small-scale, retrofit/expansion and local deployments of wireless building automation systems. If we assume that building automation systems will leverage the benefits of wireless communication, then we must ask what

protocol(s) best delivers the needed reliability, interoperability and flexibility? What combination of network architecture, hardware and software is ideal, given limited capital budgets and lack of dedicated system administration staff in smaller-scale deployments? From this examination, a picture emerges of building automation that is radically different from the current approach. A key part of the solution is decentralization, with system “intelligence” devolved to controllers. Another guiding idea is embedded— all formerly server-based functions, including control, communication, protocol integration and even data management, are incorporated within controllers’ real-time software. Another characteristic is multi-protocol, with the system leveraging the best features of heterogeneous standards (namely ZigBee, EnOcean, CANbus and BACnet/IP).

The Challenge: Control System Functions

Conceptually, a Control System performs four functions: data management, communication, control and “intellectualization,” as shown in Figure 1. Data management involves storing and retrieving data for internal (network) and external (user) needs, and presenting selected data to users. This is typically performed by a server-based database and client software. Local data storage at the controller level is generally limited to control variables. Communication implies data exchange between network components as well as between networks. Dedicated networking devices manage communications and are overseen by the server. Interconnection between networks and/or protocols may involve additional dedicated equipment (bridge, bus) or software. Control is performed at the field level. Dedicated controllers are used to implement command strategies and interact with the physical world. And finally, intellectualization is the “intelligence” needed by a system to solve, interpret or otherwise translate inputs into a command or an action. A Control Network also traditionally combines multiple “control levels,” each requiring a different type of equipment. A typical architecture calls on three general types of equipment: server, networking and controller. Figure 2 illustrates several of the major cost factors in traditional building automation. First, all those varied pieces of hardware must be purchased! Second, skilled personnel are needed to make devices talk to each other by wire or wirelessly. Note that the control functions shown in Figure 1 are spread out across the different levels and devices of Figure 2. Data management “lives” on the server. Control resides within the controller. With every new deployment, integration


Technology deployed

must take place both within the communication function (crossnetwork / cross protocol integration) and between functions (network / device integration). Yet another implied cost in Figure 2 is bandwidth. Most existing controllers are dumb, relying on round trips to the server or PLC for changes in variables and any other “intelligence.” Protocol integration is performed on the server, so that system functions requiring interoperability must communicate through this central point. Bandwidth demands can quickly overwhelm the resources offered by ZigBee and other wireless personal area network (WPAN) standards.

The Solution: “Smart” Controllers, Decentralized Control Networks

A new approach, oriented toward smaller and retrofit deployments, gathers previously dispersed functions onto the controller itself. Embedded controller software enables collaboration by providing a common high-speed data exchange scheme for all functions referred to as the “sharing kernel,” as presented in Figure 3. Characteristics of the functional modules within this architecture include five elements. The first, the communicate module, is the network’s protocol converter and runner and is embedded in the controller as an embedded software package that interacts with the other modules through the kernel. It can convert to/from multiple protocols, as long as necessary drivers are provided. The communicate module also replaces dedicated networking equipment such as routers and bridges. It is “aware” of other controllers, and contains full network mapping. The intellectualize module handles the task of implementing a sharing kernel for its controllers. The controller is guided by processes defined in a lightweight scripting language. The language must offer relatively simple syntax and a good syntax checker that enables non-programmers to configure building processes such as scheduling the operation of a HVAC system. For this function, SCL Elements has found the Lua scripting language to provide the required combination of performance, ease of use and resource demands (memory and CPU). A Lua extension called LuaC (Lua for Control) was developed to add useful libraries and tools, including a real-time task scheduler that allows easier handling of time-based functions in building automation systems. The manage data module is the memory of the embedded controller. Managed data includes control variables and history, state and communications/routing data. The module can filter or format records quickly, and provide results to the other modules through the sharing kernel. Challenges include providing data management with the reliability and sophistication of a true database management system (DBMS) while avoiding the size and performance overhead of DBMSs that are designed to store records on permanent media. In SCL Elements’ controllers, eXtremeDB from McObject was successfully used as an embedded in-memory database system (IMDS). eXtremeDB’s

The database contains everything from temperature sensor values to ventilation control motor speeds, to spatial location and network interfaces and addresses for the various nodes. For managing networking data, a useful eXtremeDB feature is its support for the Patricia trie, a specialized database index that is particularly effective in sorting hierarchical data such as IP addresses. The role of the control module is to implement the controller’s physical interaction with the outside world, managing electronics input/outputs and handling any electronic interface. It is also responsible for applying user-selected control strategies (PID Sets, Neural Networks). At the center of these modules is the sharing kernel, which is responsible for interaction between any internal or networked functional modules. Under this design, smart controllers do the work previously performed on the server, PLC and other components, and in fact, eliminate the need for these other devices. Functions that previously required round-trip communication with the system’s “brains” are now handled on controllers. The tree-like layout of existing building automation systems is flattened to just two levels: smart controllers that communicate among themselves, and with end devices such as HVAC and lighting systems. Because every controller has the intelligence to work autonomously, a control system can be initiated with just a handful of controllers. Gone are the server software licensing, internetworking and other up-front costs. Software functions are embedded, removing much of the integration chore. Elimination of these obstacles makes this a cost-effective solution for smaller buildings. To a large extent, the data set managed by the eXtremeDB embedded database on one controller is duplicated on all others. This provides resiliency: in the event of failure, a controller can

be reprovisioned or replaced by another unit on the network. But this flattened, server-less architecture populated by smart controllers is only part of the solution.

Communication: Supporting a ‘Dream Team’ of Standards

Wireless control systems generally, and wireless building automation networks in particular, offer a jumble of available communication protocols. Supporting all would require overly complex integration logic, driving up controller hardware costs. Allowing too few eliminates interoperability as well as strengths residing in specific standards. SCL Elements analyzed the tradeoffs and assembled a “dream team” of protocol support on a single wireless controller board, optimized for cost-effectiveness, reliability and efficiency. The EnOcean wireless bus allows communication with batteryless and ultra-low-power devices, at distances of up to 50 meters from the controller. Typical uses include switches, relays or thermostats. The data rate is low. Major benefits include no power requirements for controlled devices, and elimination of cabling cost. The ZigBee protocol covers a wider wireless range through meshing. It is used for communication between controllers, including collaboration through the sharing kernel. ZigBee’s mesh network design adds resiliency: if one network node (controller) dies, the rest can remain active. ZigBee also handles commu-

nication between controllers and powered devices (plug-in and battery). The greatest challenge that people will point to in this design is limited available bandwidth. SCL Elementsâ&#x20AC;&#x2122; solution, called CAN2GO, addresses this in two ways. First, the decentralized network design in itself frees bandwidth by eliminating a great deal of network traffic centered on the server. Second, data exchanges are implemented over an open binary XML scheme tagged as BInary LIquid XMLâ&#x20AC;&#x201D;or BILI for shortâ&#x20AC;&#x201D;which enables bandwidth preservation as well as easy communication monitoring. The CANbus is used for wired local communication when high data rates and high reliability are required, or where wireless communication is impossible, such as in Faraday cage conditions. For example, a point-to-point connection might be implemented through a particularly thick wall. Instead of setting up a separate, wired network, two sections of a wireless network can be connected via a single wired connection. CANbus can also be used to mechanically add extension modules on the fly to provide additional functionalities (I/O, interface, etc.) to the system. With its origins in automotive networking, CANbus is highly reliable and can transmit a signal more than a full kilometer without amplification. While CANbus is new in building automation systems, the embedded protocol integration within each controller makes it a plug-and-play proposition for integrators, with CANbus becoming â&#x20AC;&#x153;just another portâ&#x20AC;? on the controller. Ethernet/IP, of course, is the building automation systemâ&#x20AC;&#x2122;s â&#x20AC;&#x153;windowâ&#x20AC;? onto the outside world. Through this protocol, the system can be plugged into a LAN interface with Building Automation and Control net (BACnet/IP)-compatible hardware or soft- Untitled-6 ware, SQL databases and with applications that consume XML or support OLE for Process Control (OPC). Ethernet/IP enables access to an embedded Web-based GUI, which in CAN2GO provides the management interface for entire building automation systems. Because all controllers are connected, Web-based access to one node enables the user to â&#x20AC;&#x153;seeâ&#x20AC;? all other nodes and to accomplish tasks ranging from configuring controllers, to designating a master schedule for a propertyâ&#x20AC;&#x2122;s HVAC, lighting, security systems. BACnet/IP compatibility ensures seamless integration with existing building automation infrastructure. The CAN2GO solution relies on some â&#x20AC;&#x153;piecesâ&#x20AC;? that are open standards (EnOcean, BACnet, ZigBee); several third-party components (the eXtremeDB in-memory embedded database, Lua scripting); and a few patented elements. The most dramatic change from the past, though, is likely the ability to migrate processing intelligence from servers and PLCs to controllers, and the resulting flattening of the network. This model is shown in Figure 4 and we believe it represents the future of building automation systems.

TECHNOLOGY Eight New FMC Boards Offer up to 5 Gig Samples/s

A line of eight new Analog-to-Digital / Digital-to-Analog Boards is based on the FPGA Mezzanine Card Standard or FMC, the new open industry standard developed by a consortium of companies working through the ANSI/VITA organizations, as defined in the ANSI/VITA 57/1 2008 Specification. FMC modules are designed to connect to FMC-compliant carrier cards in the CompactPCI, VPX or PCI express form factors. The FMC Series cards from 4DSP offer a large range of bit-width and sample rates. They offer unique features such as a user-selectable option to have data sampled by an internal clock source (optionally locked to an external reference) or use an externally supplied sample clock. A trigger input for customized sampling control is also available. The I/O connections are on the front panel as per VITA 57.1. Cascading multiple FMC boards for synchronized high channel count is possible. The 4DSP FMC Series cards are equipped with power supply and temperature monitoring with several power-down modes to switch off unused functions, reducing system level power and heat—features that are well suited for software defined radio (SDR) and similar applications where battery or other low-power sources are required. The 4DSP Series FMC cards are ideal for man-pack, ground mobile vehicles, UAVs and other airborne applications where limited power sources effect mission range and on-station mission time. The boards are also available with Mil-I-46058c-compliant conformal coating for hostile environmental applications.

SATA Solid-State Drive Provides Higher Endurance and Capacity

A next-generation enterprise-class solidstate drive (SSD) is available in 1.8” and 2.5” form factors. The XceedIOPS SATA from Smart Modular Technologies is offered with either single-level cell (SLC) or enterprisegrade multi-level cell (E-MLC) NAND technologies. The XceedIOPS SATA integrates EMLC technology, which provides significantly more endurance than SSDs based on commercial MLC NAND flash. Endurance for E-MLC is specified at 20,000 program/erase (P/E) cycles, whereas current-generation commercial MLC demonstrates 1,500 or 5,000 P/E cycles, depending on the NAND flash vendor. The combination of the SF-1500 processor’s minimal write amplification and E-MLC flash enables the XceedIOPS SATA SSD to handle the most demanding workloads. For example, a 5-year lifetime can be easily achieved with a 400 Gbyte XceedIOPS SATA in an environment that demands 250 Mbyte/s sustained write and a 40% duty cycle. Featuring a SATA 2.6 interface and support for native command queuing (NCQ), the new XceedIOPS SATA 1.8” and 2.5” SSDs are optimized for performance up to 30K IOPS random read/write, 250 Mbyte/s sustained read/write and high capacity up to 400 Gbytes.

The implemented Intel Turbo Boost Technology provides an on-demand boost in the clock speed for one processor core if the other core is less utilized. This new feature improves the computing performance by as much as 25%â&#x20AC;&#x201D;as measured by congatec during benchmark testing. In order to keep the power consumption at about the same level as the predecessor generation, the CoreT i7 supports new power management states. The C6 state, already known from Intel Core processors, saves the architectural state to a dedicated SRAM. Then the cores can be switched off to reduce the current to almost zero. The independence of the C6 states for each core boasts even greater power savings for the platform. Five PCI Express lanes, eight USB 2.0 ports, three SATA, one EIDE and a Gigabit Ethernet interface allow for fast and flexible system extensions. Fan control, LPC bus for slow-speed extensions and Intel High Definition Audio complete the feature set. congatec, Cardiff-by-the-Sea, CA. (760) 635-2600. [www.congatec.us].

Low Profile Heat Sinks Cool Hot Components in Constricted Packages

A line of lower height heat sinks is designed for cooling ICs and other hot components in narrow packaging and low airflow velocity conditions. The maxiFLOW heat sinks from Advanced Thermal Solutions feature a spread fin array that maximizes surface area for more effective convection (air) cooling. Standard sink heights are as low as 9.5 mm. The heat sinks are fabricated from extruded aluminum, which minimizes thermal resistance from the base to the fins and minimizes weight. Tests on maxiFLOW heat sinks using an airflow rate of just 100 linear feet per minute (lfm) show that device junction temperatures (Tj) can be reduced by more than 40 percent below the temperatures achieved using other heat sinks. Low profile maxiFLOW heat sinks are provided pre-assembled with ATS maxiGRIP mounting hardware. This attachment system includes a plastic frame clip that snaps securely around the component. A stainless steel spring clip runs through the fin field and fastens to the frame. The result is steady, even mounting pressure with no holes in the PCB. These assemblies meet Telcordia GR-63-Core, ETSI 300 019 and MIL-STD-810 shock and vibration testing standards. A thermally conductive, phase-change interface pad maximizes the heat transfer from component to the cooling solution. Pricing for ATS low profile maxiFLOW heat sinks starts at less than $10.00 each, which includes the mounting hardware and phase change thermal interface material. The heat sinks are also available without the mounting system. Advanced Thermal Solutions, Norwood, MA. (781) 769-2800. [www.qats.com].
