With the wide applications of wireless communication in the air inter-face, needs secure connections, efficient decryption and strong authentication mechanisms. In general, authentication procedure adds extra messages to the original message flow and results in throughput reduction/ increase in processing time. Reducing the processing time spent on authentication procedure is very important for a smooth and seamless hand over. However there is a cost, while deploying security on a network in terms of processing time. Extensible Authentication Protocol - Transport Layer Security (EAP-TLS) is a robust authentication mechanism used in Beyond 3G (B3G) environments and it is seconded by Public Key Infrastructure (PKI).
