WIMAX- Worldwide Interoperability for Microwave Access is going to be an emerging wireless technology for the future. Wireless networking market is thriving because of increasing popularity of Broad Band internet. Wireless network is not completely secure because of rapid release of new technologies, lack of physical infrastructure and market competition. It is (WiMAX) a new technology; not deployed widely to justify the evidence of threats, risk and vulnerability in real situations. Although authentication process is a key to secure access in wireless network, the security sub layer of IEEE802.16 employs an authenticated client server key management protocol in which the Base Station (Server), controls the distribution of keying materials to the Mobile Station( the client). In this paper, an overview of authentication framework is first discussed and several threats on authentication process is later interrogated. Finally, possible solutions to overcome them are inaugurated.
