Examines the security mechanisms and protocols for thwarting attacks on emerging wireless networks including wireless LANs, sensor networks, mobile ad hoc networks and wireless cellular standards. Specifically, examines security primitives including confidentiality assurance, integrity and authentication in the context of different wireless networks. Block and stream ciphers, such as the Data Encryption Standard, Advanced Encryption Standard and RC4 are studied. Evaluates Public key cryptography (PKC) and its associated algorithms (RSA). Discusses approaches to integrity assurance in the form of cryptographic hash functions. Examines all of the above factors in the context of a variety of network topologies to include personal area networks (PAN-Security in Bluetooth), wireless local area networks (WLAN), and wireless metropolitan area networks (LTE and WiMax). Analyzes and compares protocol implementations such as Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA/WPA2). Also analyzes security in wireless cellular standards, including 2G (GSM), 3G, and 4G(LTE). The course studies communication vulnerabilities in wireless systems with example attacks such as Denial of Service (DoS), replay, and man-in-the-middle (MITM). Security in mobile ad hoc networks, including wireless sensor networks and Internet of Things (IoT) is also studied.
