Executive Summary

Here is a new technology that can provide broadband access at a high bandwidth. It's called WiMax (Worldwide) Interoperability for Microwave Access. The availability of microwaves towers provides a very cost effective for delivering high bandwidth in metropolitan cities. It is a multi-hop network where security is a major issue in designing such networks. Designing a secure WiMax is a major research challenge that has been approached in recent publications. This paper discusses security changes of WiMax and suggests a new authentication protocol for it. The next generation of the IEEE802.16/WiMAX will be the most important component of the wireless system. The standard version of IEEE 802.16/WiMAX employs advanced radio transmission technology to provide well defined quality-of-service broadband wireless capabilities. The IEEE802.16 physical layers have a lot of flexibility in its four shapes. The operation on the spectrum allocation will have a wide range in its channel bandwidth, frequency division duplex, and time division duplex. These four modes layers have significant tasks such as initial ranging, bandwidth requests, connection channel, and registration. Although there is a variation types for the physical layer, the security protocol will be the same. However there are some protocols that could interfere with the security of the WiMax network. In the recent years, the IETF had concluded that researchers shall focus on what causing these attacks and that they need to find a way through security, to make WiMax network much secure.
