Improving Security Levels of IEEE 802.16e Authentication by Diffie-Hellman Method

In this paper, the authors proposed an authentication method according to Diffie-Hellman. First, they introduce different methods for authentication in IEEE.802.16 then they proposed an authentication method according to Diffie-Hellman and in the last they compare different methods for authentication to improve security in IEEE802.16e. CPN is a useful for simulation and compare protocol together so they use CPN tools in this paper. The importance of IEEE 802.16, Worldwide Interoperability for Microwave Access (Wimax) is growing and will complete with technologies such as 3G. The acceptance and adoption of technologies also depend on security.
