cryptanalysis and Improvement of a Recently Proposed Remote User Authentication Scheme Using Smart Cards

S. Sharmila Deva Selvi and S. Sree Vivek

Abstract

Recently Debasis et al[1] proposed an improvement to prevent offline attack in Fang et al’s[2] scheme, where [2] was an improvement of Das et al’s[3] scheme. However the improved scheme is insecure against side channel attack. In this paper we propose an enhancement for [1]. The enhanced scheme is secure against substitution, impersonation, spoofing, replay, side-channel and password guessing attacks.
