Security Analysis of an Authentication Scheme Using Smart Cards
Gaurav Tiwari and 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.
