Abstract : Broadband wireless networks namely wireless interoperability for microwave access and long term evolution utilizes the EAP and EPS mechanisms for authentication. However, these mechanisms incur considerable delay during handoffs. This delay during handoffs results in service disruption which becomes a severe bottleneck. To overcome this delay, our article proposes (UPP-KC) a key caching mechanism based on user path prediction. If the user follows the predicted path, he/she bypasses the normal authentication mechanism and obtains the necessary authentication keys directly. Through analytical and simulation modeling, we have proved that our mechanism effectively decreases the handoff delay, thereby achieving fast authentication without compromising on the security standards
