The design of a Trusted Authentication scheme for Wimax Network

As a promising broadband wireless technology, WiMAX has many salient advantages over such as: high data rates, security, and mobility. Many sophisticated authentication and encryption techniques have been embedded into WiMAX but it still exposes to various attacks in. IEEE802.16 provides a security sublayer in the MAC layer to address the privacy issues across the fixed BWA (Broadband Wireless Access). In this paper, we first overview the IEEE802.16 standard, and then investigate possible attacks on the basic PKM protocol in IEEE802.16. We also give possible solutions to counter those attacks.
