• Introduction to wireless networks security: Wired vs. wireless network security, categories of Threats and the OSI model, Vulnerabilities, Countermeasures, Security architectures.
• IEEE 802.11 standard security issues: Authentication and authorization mechanisms, Confidentiality and Integrity, pre-RSNA protocols (WEP), TSNs (TKIP), RSNA (802.11i), Key management, Threat analysis and case studies.
• Cellular networks security (3GPP): Security issues, Network access and Authentication mechanisms, Key hierarchy and administration, Encryption, Integrity and user Privacy, Inter and Intra-network security, classification of attacks.

This course covers the major security and privacy topics in wireless and mobile networking. The main learning objectives of this course are:

• To conceptualize the idiosyncrasies of wireless terrain in terms of security and privacy.
• Τo impart state-of-the-art technologies of wireless network security.
• Τo analyse the various categories of threats, vulnerabilities, countermeasures in the area of wireless and mobile networking.
• Τo familiarize students with the issues and technologies involved in designing a wireless system that is robust against attack.

The course considers basic security topics and technologies in the following standards: 3GPP GSM/UMTS/LTE, IEEE 802.11. The emphasis is put on the security issues of MAC and upper layers. The aforementioned objectives are fulfilled through course lectures, paper readings, and projects.
