摘要
Abstract
Remote authentication scheme allows a remote server and the user to realize mutual authe-ntication through the unsafe channel. Tang Hongbin et al claim that there are some security problems in Chen et al’s scheme, such as loss of smart card attack, replay attack, etc. It proposes an improved remote authentication scheme based on smart card. But Tang Hongbin et al introduce timestamp mechanism to resist replay attack. This paper proposes a remote asynchronous authenti-cation scheme based on smart card. The scheme doesn’t need to sonsider clock synchronization and can resist all men-tioned attacks, operation is easier and the performance cost is not increased.关键词
