In this article, we propose a new remote user authentication scheme using smart cards. The scheme is based on the ElGamal's public key cryptosystem. Our scheme does not require a system to maintain a password table for verifying the legitimacy of the login users. In addition, our scheme can withstand message replaying attack.
In 2000, REF proposed a remote user authentication scheme using smart cards in which they had removed the risk of modified password table present in Lamport's scheme.
