An Enhanced Remote User Authentication Scheme

Keerti Srivastava, Amit K Awasthi, and R. C. Mittal


In 2003, Shen et al [4] proposed a timestamp-based password authentication scheme in which remote server does not need to store the passwords or verification table for users authentication. Unfortunately Wang and Li[6], E.J.Yoon [8],Lieu et al.[3], analyzed independently the Shen Lin Scheme [4] and was found to be vulnerable to some deadly attacks. In continuation to it, this paper analyzes few attacks and finally proposes an improved Timestamp- based password remote user authentication scheme so that it can withstand the existing forged attacks.
