A NEW MECHANISM TO SOLVE IEEE 802.16 AUTHENTICATION VULNERABILITIE

Wi-Max (Worldwide) Interoperability for Microwave Access is a new technology that can provide broadband access at a high bandwidth.The availability of microwaves towers provides a very cost effective for delivering high bandwidth in metropolitan.Wi-Max is a multi-hop network where security is a major issue in designing such networks.Designing a secure Wi-Max is a major research challenge that has been approached in recent publications.In this paper we are discussing security changes of Wi-Max and suggesting a new authentication protocol.
