A Security Architecture for Wimax Networks

Wimax is one of the fast growing technologies in the world as compare to other wireless networks. IEEE has defined standard IEEE 802.16 for Wimax. Wimax growing rapidly due to the services it’s provides and long range accessibility, but still Wimax facing a lot of security issues and threats like jamming , DDOS , Rogue Base station attack ,Reply Attack and so on.Wimax furnish different security mechanism for unauthorized access ,Encryption, Authentication etc. and several security architecture , mechanism areproposed. But still Wimax is under attack like Rogue Base station Attack And Reply Attack.so in this paper we proposed a new and unique security model and Encryption technique on the basis of existing model to secure Wimax from Rogue Base station Attack and reply attack. We perform the simulation through NS-2
