摘　　要：介绍了2006年Manik提出的远程认证体制,对其存在安全缺陷进行了详细分析。在此基础上,提出一种改进的远程认证体制。该体制使用用户智能卡生成一个立即数并使用两种杂凑运算,以改进整个认证体制的安全性能和计算性能。与现有的其它远程认证体制相比,提出的远程认证体制还实现了用户和远程服务器之间的双向认证。A remote authentication scheme proposed by Manik in 2006 is introduced, and some security flows in this scheme is analyzed in detail. Based on this discussion, an improved remote authentication scheme is proposed. To improve the whole security performance and reduce the computation cost of this scheme, the individual smart card of a user generates a nonce and executes two kinds of hash operations, Compared with the Manik＇s scheme, the proposed scheme can implements mutual authentication between the user and the remote server, which is very suitable to the distributed network environment.
