Authentication System based on Hash Function - A Review

Abstract

Authentication is the process whereby the system identifies legitimate users from unauthorized users. It is the process in which a user identifies his/her self to the system. How effective an authentication process is determined by the authentication protocols and mechanisms being used. Windows Server 2003 provides a few different authentication types which can be used to verify the identities of network users.This paper described a new simple and efficient Grid authentication system providing user anonymity. Our system is based on hash function, and mobile users only do symmetric encryption and decryption. In our system, it takes only one round of messages exchange between the mobile user and the visited network, and one round of message exchange between the visited network and the corresponding home network.
