R.Narmadha, Dr.S.Malarkan, Dr.C.Ramesh . Performance Analysis of Signaling Cost on Eap-Tls Authentication Protocol Based on Cryptography. International Journal of Computer Applications. 33, 7 ( November 2011), 18-23. DOI=10.5120/4032-5771
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).EAP-TLS authentication protocol supports a large number of cipher suites. By using Advanced Encryption Algorithm (AES) and Diffie Hellman -RSA key exchanges, a secure communication were established in B3G networks. This paper formally analyzes EAP-TLS message flow with cryptography algorithms and also numerical results are evaluated with the signaling cost. In addition to that PKI based solution has been discussed against Extensible Authentication Protocol –Authentication key Algorithm (EAP-AKA) procedures. The proof result shows that the authentication process of EAP-TLS can guarantee the security of wireless communication
