SECURE, EFFICIENT AND CERTIFICATELESS AUTHENTICATION SCHEME FOR WIRED AND WIRELESS NETWORKS

In wireless Local area network if any user needs to access resources first, they must be authenticated, for authenticating the users in WLAN, the authentication framework that has been extensively used is EAP known as Extensible authentication protocol. There are widely used authentication mechanisms that have been implemented on extensible authentication protocol framework called extensible authentication protocol methods. In RFC 4017 the specification for extensible authentication protocol methods has been defined but few features like low computation for deriving keys, forward secrecy, efficiency, providing strong security, and re-authentication (avoiding execution of full authentication) which is very much desired which are excluded. In this paper, we will show the comparison of our proposed method named REAP that satisfies the requirements specified in RFC 4017 and how authentication time, authentication traffic and how processing time is reduced using symmetric key cryptography.
