Abstract: The much anticipated technology of mobile WiMAX, the worldwide interoperability for microwave access, aims to provide seamless support to its users but an inevitable is that the long delay which occurs during the handoff management in every network process. Secure key distribution is done by private key management version 2 (PKMv2) with extensible authentication protocol (EAP). Handovers may cause delays and packet losses that affect real-time communication performance. Hence, we optimise the services by introducing new ideology in key caching mechanism which minimises the authentication cost and processing time consumes 56.8% than earlier approach. This can be investigated analytically and the network entry process can be simulated through MATLAB GUI model with MySQL as the backend for storing respective ID. The simulation is carried with the network simulator. This paper proposes three types of key caching. This approach is justified through its timing analysis result which indicates that the key caching mechanism can efficiently swift the handoff processes.
