碩士 === 長庚大學 === 資訊管理學研究所 === 97 === WiMAX (Worldwide Interoperability for Microwave Access) is an emerging wireless communications technology for Broadband Wireless Access (BWA) with wide bandwidth and long distance. So it can be used to deploy Wireless Metropolitan Area Networks (WMANs) and solve the problem of “last mile”. Although IEEE 802.16e-2005 amendment enhances the security of PMP (Point-to-Multipoint) mode in IEEE 802.16-2004, the security problems in mesh mode still exist. This paper improves “Node Authorization” and “Establishing Link to Neighbors” in IEEE 802.16e PKMv1 with a shared authorization key by new node and authorization node, and uses the Token generated by authorization node to identify that if both sides in communication have authorized. In according to the result of performance analysis, the computation time of client nodes in this paper has less than other literatures.
