Authors: Jue-Sam Chou, Chun-Hui Huang, Cheng-Chung Ding
Abstract:In 2004 and 2005, Tsaur et al. proposed a smart card based password authentication schemes for multi-server environments, respectively. They claimed that their protocols are safe and can withstand various kinds of attacks. However, after analysis, we found their schemes each have some secure loopholes. In this article, we will show the security flaws in these two protocols.
