End-to-end security comparisons between IEEE 802.16e and 3G technologies

Security measures of mobile infrastructures have always been important from the early days of the creation of cellular networks. Nowadays, however, the traditional security schemes require a more fundamental approach to cover the entire path from the mobile user to the server. This fundamental approach is so-called end-to-end (E2E) security coverage. The main focus of this chapter is to discuss such architectures for IEEE 802.16e (Mobile-WiMAX) and major third generation (3G) cellular networks. The E2E implementations usually contain a complete set of algorithms, protocol enhancements (mutual identification, authentications, and authorization), including the very large-scale integration (VLSI) implementations. This chapter discusses various proposals at the protocol level.
