The Mobile WiMAX IEEE 802.16e is a neoteric technology providing broadband data access to mobile and stationary users while supporting handover and roaming capabilities. In the area of security aspects, Mobile WiMAX exhibits vulnerabilities while adopting improved security architecture. Bandwidth is an additional overhead in reducing these vulnerabilities. To compensate bandwidth and security, this project focuses on reducing the security vulnerabilities in the initial network entry process and access network of the WiMAX domain with a view to reduce the memory required for key management. This paper proposes the usage of 1.Modified Diffie-Hellman algorithm and 2.Device certificate for key exchange process to provide secure authentication and 3.Compression technique to reduce the memory space and the transmission bandwidth. The 802.16e mobile WiMAX model is implemented using Qualnet and security enhancement is implemented using MATLAB.MYSQL is used as the database for Key storage. This proposed work enhances the security of the WiMAX network and reduces at least 50% of the bandwidth.
