Security Analysis of an Authentication Scheme Using Smart Cards

Gaurav Tiwari, Amit K. Awasthi, and Neha Shukla

Abstract

In 2010, Sood et al [3] proposed a secure dynamic identity based authentication scheme using smart cards. They claimed that their scheme is secure against various attacks. In this paper, we improve their scheme for outsider attack as well as insider attack. To remedy these security flaws, an improved scheme is proposed to withstand these attacks.
