Applied Cryptography for Wireless Networks
Exam Questions
Course Introduction
This course explores the principles and practices of cryptographic techniques specifically tailored for wireless network environments. Students will examine modern encryption algorithms, key management protocols, and authentication mechanisms that address the unique security challenges posed by wireless communication, such as eavesdropping, spoofing, and denial-of-service attacks. Emphasis is placed on the practical application of cryptographic solutions in wireless protocols like Wi-Fi and mobile networks, as well as the design of secure systems for emerging wireless technologies. By the end of the course, students will be equipped to evaluate, implement, and enhance cryptographic protections in real-world wireless network scenarios.
