"The IEEE 802.16 is the standard for the Wireless Metropolitan Area Network (WMAN), better known as WiMAX (Worldwide interoperability Microwave Access). WiMAX is the next generation technology that offers broadband wireless access over long distances. As WiMAX standards expand from considering a fixed line-of-sight propagation and point-to-multipoint infrastructure high frequency system to a lower frequency non-line-of-sight mobile system, WiMAX is open to more security threats than other wireless systems. This paper presents the different security issues present in privacy and key management protocol along with the proposed solutions."
