It’s Fall 2024 at the NYU Center for Cybersecurity, and with the launch of a new semester comes a new crop of students and a change in the Center’s leadership structure. It’s time to wish continued success to the 2023-2024 Ph.D. graduates who have moved out into the world, while acknowledging the new partnerships and opportunities awaiting CCS researchers in the year ahead, and to mark the appointment of a new co-director. As the leaves fall and the planet spins us into cooler days, CCS stands ready to turn the page for the next evolution of secure practices and products.

A NOTE FROM THE EDITOR-IN-CHIEF Over the past few issues of CyberByte, we have highlighted the diverse number of research topics currently under investigation by the faculty and students of the Center for Cybersecurity. To date, we have spotlighted research initiatives to protect sensitive data, supply chains, critical infrastructure, the Internet of Things, and, most recently—in a look at deepfakes and disinformation—truth itself.

The problem in compiling stories for these topical sections is that the lines distinguishing areas of inquiry are often not very clear. Indeed, as the field of cybersecurity evolves, it increasingly involves deploying multidisciplinary strategies that criss-cross established lines of research. Thus, when we label our research focus for these issues, the stories we run may seem to seriously stretch the traditional definition of that topic.

This issue’s featured Research Topic is “Hardware Security,” but, as you will see, the work reported here reaches beyond designing more efficient computer chips, or more sophisticated system architectures. For instance, Ph.D. student Jianqiao “Cambridge” Mo is enhancing privacy-preserving computation work using a hardware-software co-design accelerator. Developed in the Brooklyn Application, Architecture, and Hardware Lab (BAAHL), under the direction of CCS faculty member Dr. Brandon Reagen, the accelerator known as HAAC maximizes performance while maintaining programmability.

Another example featured here comes through CCS’ long-running interdisciplinary initiative with the Mechanical and Aerospace Engineering Department at Tandon.

Professor Nikhil Gupta, working with Priyanka Nama, a visiting scholar from the Department of Education, Government of Rajasthan in India, introduces a new initiative that boosts security in smart homes by precisely targeting potential physical defects and vulnerabilities. As Gupta and Nama described in a recent issue of IEEE Transmitter, these enhanced systems monitor factors that can predict cracks, foundation settling or shrinkage, water damage, and other issues that can threaten the structural integrity of smart buildings.

There’s a lot more to discover in this issue of CyberByte. We chat with Ph.D. student Caleb Beckwith, who just received a grant from the American Society for Nondestructive Testing (see Ph.D. Profile), and say farewell to our 2024 CCSaffiliated Ph.D. graduates. We also highlight CCS participation in two significant government-funded projects, one in infrastructure protection and the other in chip security, and learn about the first research collaborations to be undertaken under a newly signed agreement between NYU and the Indian Institute of TechnologyKanpur. Lastly, we congratulate CCS research faculty member Dr. Damon McCoy, who has taken the reins as our new Center Co-Director (See Hello/Goodbye article, starting on pg. 4). Enjoy!

RESEARCH FOCUS: CREATING, BUILDING, AND PROTECTING STRONGER AND SMARTER HARDWARE Though previous issues have explored contributions of CCS faculty and students to strengthening the security of hardware, we are circling back to this topic to examine it from a broader perspective. Both in the summaries below, and in work highlighted later in these pages, this issue looks at changing approaches to hardware security, including new methods that blend traditional security strategies with new methods borrowed from other disciplines.

Here are brief summaries of a few such projects in development in CCS labs.

MAKING SMART HOMES “SMARTER” Research summary submitted by Dr. Nikhil Gupta, Professor of Mechanical and Aerospace Engineering, NYU Tandon Smart homes incorporate a variety of sensors and devices that enable automatic functioning for comfort and convenience.

However, they often lack the necessary technology to monitor the health of a building’s critical systems, such as electrical, plumbing, and heating and ventilation. A potential solution could lie in the Structural Health Monitoring (SHM) systems already used to monitor infrastructure—such as bridges, dams and pipelines. In an article published on May 9 in IEEE Transmitter, Priyanka Nama, a visiting scholar from the Department of Education, Government of Rajasthan in India, and myself suggest such systems could be used to assess the health of critical systems in homes in real-time. SHM systems can monitor load, vibrations, displacement, strain, moisture and other factors using piezoelectric materials, accelerometers, ultrasound, strain gauges and fiber optics. In doing so, sensors can identify and address structural integrity issues in smart homes—including cracks in foundations, walls and ceilings, and roofs, and hidden leaks leading to water damage and potential mold growth—before they escalate. Furthermore, SHM systems can be adapted to consider their integration with smart home networks, wireless connectivity, simplified installation, user-friendly interfaces, customizable monitoring parameters, costeffectiveness and scalability By aggregating data from several houses in a neighborhood, SHM sensors can provide crucial information about a broader range of issues, such as soil quality change over time. Future work in adapting SHM systems should explore the best methods for sharing the data for beneficial use, and protecting it from malicious use.

IMPROVING SECURITY OF 3D-PRINTED PARTS THROUGH ENHANCED COMMUNICATION Tandon research initiatives in hardware security have also benefited over the years from strategic partnerships with industry, government agencies, and other academic institutions. Recently, a government-funded initiative to better protect 3-D printed parts was launched, and two CCS-affiliated Professors, Nikhil Gupta and Ramesh Karri, plus Dr. Nektarios Tsoutsos, a Tandon Ph.D. graduate who is now an Assistant Professor at the University of Delaware, are part of the team.

The team will be tackling a significant hardware security challenge. As demand for computer-designed 3D-printed parts in industries like aerospace and automobiles has grown, so has the likelihood of

human error can expose security-critical operations, and induce dire consequences.

Under a three-year grant from the National Science Foundation, the team will be led

by Dr. Narasimha Reddy, a professor in the Department of Electrical and Computer Engineering at Texas A&M University.

According to Dr. Reddy, the goal of this project is to “get the people from the cybersecurity side and people from the

manufacturing side to talk to each other to create a community that’s going to be interested in solving the problems.” The community he envisions building will try to “bring people of similar interests together through workshops, conferences and student design competitions. The intent is to create several activities that spark interest in this space.” The project will also create a website to “open the lines of communication between manufacturers and researchers.”

In addition to the individuals mentioned above, team participants will include Dr. Satish Bukkapatnam, co-principal investigator and Texas A&M industrial engineering professor, Dr. Sidi Berri from The City University of New York, and Dr. Annamalai Annamalai from Prairie View A&M.

CyberByte: I’d like to start with your backstory. I understand from the profile NYU published about the ASNT award that you grew up in Columbus, OH, and completed your bachelor’s degree at CUNY CityTech. What brought you to NYC and to CUNY? Beckwith: My personal history is a bit complicated. I was born in Columbus and lived there for some time before moving to Daytona, Florida, and then to Rock Hill, South Carolina between 2005 and 2014. This was mostly due to poor economic conditions. Rather than being stuck in a single town where the jobs were limited and wages were low, my mother and father took the pragmatic approach of moving us to wherever they could have a better job. This ensured my sisters and I could have the best opportunities for our education.

During my last year of high school, my mother and I moved to Brooklyn. She is still here, working as a paralegal. I was accepted into Hofstra University in Hempstead, and attended classes there for four semesters. But, at the time my mother’s health was in steady decline and I was not comfortable commuting from Long Island to take care of her while attending school full-time. So, I transferred to the City University of New York’s New York City College of Technology in Brooklyn. Our situation was a lot better then as I was only 15 minutes away from her. CityTech also afforded me many opportunities I was not able to have at Hofstra, such as leading the school’s mechanical engineering undergraduate research club, as well as tutoring and mentoring other students.

CCS NEWS NYU ENGINEERING CELEBRATES ITS CYBERSECURITY PAST AND FUTURE Throughout 2024, NYU has been celebrating the blended 170 year engineering heritage of both the NYU School of Engineering, and Polytechnic University with which it merged in 2014. When it comes to cybersecurity, that heritage is a rich one indeed, with accomplishments that include the establishment of one of the first-ever master’s degree programs specializing in cybersecurity, and the most comprehensive student-run cyber event now known as CSAW. Thus, it’s not surprising that the field of cybersecurity is one of the areas which the university has chosen to spotlight during this celebration. This summer, NYU released a lengthy news feature highlighting the school’s unique role in advancing this fast-evolving and increasingly critical discipline.

In documenting the school’s track record in this field, the feature points to the leadership role of Dr. Nasir Memon in initiating or guiding many of the programs cited above.

Currently Interim Dean of Computer Science, Data Science, and Engineering at NYU Shanghai, Memon is honored in the article as a true “cyber pioneer.” The feature also pays tribute to NYU’s ability to “evolve education faster than threats,” and points to the significant role the school will play moving forward in training the next generation of cyber professionals. In quoting why NYU has excelled in this area, Memon observes, “You need credentials that can be obtained quickly and get you up to speed to become a useful member in the cybersecurity workforce.” NYUs programs produce cyber professionals who not only “understand the basic tools and techniques,” but also “understand the processes and are able to audit and then check for compliance and implement processes,” and “know what’s going on under the hood. That’s what it takes to create tomorrow’s protection mechanisms when technology and the threat landscape change so rapidly.”

TANDON RESEARCHERS TAKE ACTIVE ROLES IN GOVERNMENT-FUNDED, MULTIPARTNER INITIATIVES IN CRITICAL INFRASTRUCTURE AND CHIP SUPPLY Over the past year, Tandon faculty have taken major roles in two significant collaborative efforts with U.S. government agencies.

Announced in March, 2024, a grant from the U.S. Department of Energy will fund an initiative to protect critical infrastructure from cyber attacks. And, late last year, the opening of Tandon’s Nanofabrication (NanoFab) Cleanroom, a specialized research environment in which scientists and engineers can fabricate cuttingedge semiconductor chips, will facilitate the school’s contributions to the Northeast Regional Defense Technology Hub (NORDTech).

Representing the collective effort of 56 high-tech companies and educational institutions—and funded by a grant of more than $40 million from the Department of Defense’s Microelectronic Commons Program—NORDTech is one of eight regionally located hubs designed to fulfill the promise of the bipartisan 2022 CHIPS and Science Act. These hubs support research and development and workforce cultivation for chips manufacturing.

by President Biden in 2022.” The lab will facilitate these efforts through its role as a key contributor to the research and development programs of NORDTech.

This grant is one of the first major awards from the CHIPS & Science Act. It establishes the infrastructure of the hub by allowing partners—including NY CREATES, the University at Albany College of Nanotechnology, Science, and Engineering, Cornell University, Rensselaer Polytechnic Institute and IBM—to bolster workforce training programs for the semiconductor industry, and add new state-of-the-art microelectronics equipment.

At NYU Tandon alone, NanoFab will align with existing Centers such as NYU WIRELESS and the Center for Cybersecurity. It will continue to drive university leadership in quantum computing, artificial intelligence, and robotics.

In summarizing the significance of NanoFab, NYU President Linda G. Mills observes, “NYU Tandon’s new NanoFab cleanroom in Brooklyn will be a state-of-the-art laboratory where our world-class scientists, scholars and students—as well as our partners and collaborators from around the city—can harness their ingenuity and innovative prowess to advance scientific discoveries while boosting both New York’s economy and burgeoning tech sector.”

MAKING SOFTWARE UNDERSTANDABLE— AND A BIT CUDDLY AS WELL The Update Framework, a secure method for delivering software updates, has a new avatar. Tai, a juggling elephant, is one of several cloud native applications that now appear as characters in a book called “Phippy’s AI Friend.” Published by the Cloud Native Computing Foundation, a branch of the Linux Foundation, the book offers a unique way to make the worlds of artificial intelligence and cloud native applications understandable on the broadest possible level.

The basic premise of the book is that everyone has a unique purpose or function. Phippy, a simple PHP application in the form of a giraffe, is inviting friends to a birthday party in Paris. He befriends an AI generated robot named Kimani, who eventually figures out that they could detect invasive ​​entities that did not belong at the party.

The characters in “Phippy” have appeared in eight books to date. All of these characters have been “donated” to the series by the open source developers of CNCF software projects. This book marks the first appearance of Tai, the elephant embodiment of the The Update Framework, in the series. TUF, which was developed In the early 2010s

by CCS researcher Dr. Justin Cappos, is an open-source technology that secures software system updates and is now used by companies including Microsoft, Google and Amazon.

Along with the story, the book contains an activity that families can do together. By scanning a QR code or going to phippyai.com, readers can download a Scratch template that will enable them to train Kimani to scan for the invasive characters called Creepers to prevent them from coming to the party.

Written by Cassandra Yuting Chin and illustrated by Romain Thérenty, the book can be purchased directly from CNCF at https://www.cncf.io/ phippy/, or through Amazon.com at https://www.amazon.com/Phippys-AI-Friend-Workshop-Parents/dp/B0CWYF8JT6.

TANDON RESEARCH EXPO SPOTLIGHTS TWO INNOVATIVE CYBERSECURITY PROJECTS As one of the school’s seven designated areas of excellence, cybersecurity research projects are a regular feature at the Tandon Research Excellence Exhibit, held each year on the Brooklyn Promenade outside the school’s Dibner Library. According to Tandon, the exhibit “features student and faculty projects illustrating the scope of engineering, the applied sciences, and their potential for improving the world.”

CyberByte checked in with the researchers behind the two designated cybersecurity projects at the 2024 Exhibit. Here are descriptions of the projects in their own words:

“gittuf is a security layer for Git repositories that

“The project titled ‘CovSBOM: Enhancing Software Bill of Materials with Integrated Code Coverage Analysis’ presents a novel tool designed to improve the accuracy of Software Bills of Materials (SBOMs) by integrating code coverage analysis. SBOMs are critical for managing software vulnerabilities, but they often lack detailed insights into which parts of the code are actually being used, leading to inefficiencies and false positives in vulnerability detection.

CovSBOM addresses this by analyzing the specific code coverage of thirdparty dependencies within Java applications and integrating these results back into the SBOM. The tool has been evaluated on 23 large-scale applications, showing a significant reduction in false positives and enhancing the precision of vulnerability detection by approximately 72%. The project highlights CovSBOM’s scalability, usability, and its potential to improve the management of software vulnerabilities in diverse programming environments.”

enables owners of these repositories to distribute (and revoke) contributor signing keys, and define policies about which contributors can make changes to particular namespaces within the repository. This extra layer of protection is built on several key properties of The Update Framework (TUF), such as delegations, secure key distribution, key revocation, trust rotation, read / write access control, and namespaces. In addition to TUF, gittuf also builds on the Reference State Log design (described in an academic paper), which also enables protection against reference state attacks. Finally, gittuf can be used as a foundation to build other desirable features, such as cryptographic

NYU HOSTS COMPUTER ARCHITECTURE DAY In April, NYU welcomed more than 80 students, researchers, and industry experts — including representatives from Columbia University, Cornell and Cornell Tech, the New Jersey Institute of Technology, Northeastern University, Princeton University, the University of Rochester, the University of Pennsylvania, the University of Virginia, and Yale University—to the Tandon campus for Computer Architecture Day. A gathering of computer scientists drawn largely from the Northeastern seaboard, the event also attracted industry representatives from D.E. Shaw Research, Google Deepmind, IBM Research, Lucata, and Qualcomm Labs, all eager to exchange ideas with fellow computer architects.

Under the direction of Dr. Brandon Reagen, Assistant Professor of Electrical and Computer Engineering and Computer Science and Engineering, the conference provided a forum for 17 students to present their research, which ranged from unique defenses against DNN attacks, to methods to speed up Large Language Models to improve image encoding in virtual reality, to a method for creating a hardware “kill-switch” for AIs. A highlight of the program was a keynote speech by Brannon Batson of D.E. Shaw Research. Batson discussed the company’s supercomputer, known as Anton 3, and its ability to surpass supercomputers by at least 100 times in simulating various biomolecular systems. In particular, Batson pointed to the intricate interplay between hardware, software, and algorithms that enabled the computer to achieve such remarkable speedups.

The event was organized by NYU Tandon students Karthik Garimella, Jianqiao Mo, Negar Neda, Austin Ebel, Nandan Jha, and Alhad Daftardar, with support from Raquel Thompson from ECE.

AWARDS AND HONORS PH.D. STUDENT GARIMELLA RECOGNIZED FOR AI RESEARCH Karthik Garimella, a Ph.D. student in the Department of Electrical and Computer Engineering was recently named a “Rising Star” by MLCommons (see https://mlcommons.org/), an AI consortium dedicated to “encouraging open collaboration and improving the accuracy, safety, speed and efficiency of AI technologies.” The “Rising Star” designation honors young researchers working at the intersection of machine learning and systems, and supports their development through access to workshops, networking opportunities, and other resources. According to Vijay Janapa Reddi, MLCommons VP and Research Chair and steering committee member of the Rising Stars program, “by nurturing and supporting the next generation of researchers, both domestically and globally, we aim to foster an inclusive environment where these individuals can make groundbreaking contributions that will shape the future of ML and systems research.”

Garimella, who came to Brooklyn for his doctoral studies after earning a bachelor’s degree in physics from Hendrix College and a master’s degree in computer engineering from Washington University in St. Louis, earned the honor for his investigative work in protecting the privacy and security of machine-learning technologies. Now working under the guidance of Assistant Professor Brandon Reagen, a faculty member of NYU’s Center for Cybersecurity, Garimella is particularly focused on closing a “privacy loophole” created in the use of cloud-based applications, including social media. As he explained to NYU News, this loophole is created by the way AI shares information. “You type in a prompt, and it gets sent to the cloud, and although it’s secured during transmission, at the end of the day, the company still has access to it. This is concerning, especially if it contains sensitive or personal information.” To address this loophole, Garimella is using a number of technologies, including multi-party computation, where differing parties

His advisor was unsurprised that Garimella, who is currently interning at NVIDIA, was chosen for the competitive program.”He is a fantastic student whose academic talent, rigor, and creativity exemplify everything we hope for in a Tandon doctoral candidate,” Dr. Reagen comments. “ I predict that his work will make a major impact.”
