However,these schemes are not designed for multi-server architecture environments. In this paper, we present a remote password authentication scheme for multi-server environments based on one-way hash function. In this scheme, anyuser can freely choose his password. There is no limitation of the number of the users, and the system doesn't need to keep the passwords for the users. According to the analysis, intruders cannot obtain any secret information from the public information or transmitted messages of a user.In addition, this scheme can withstand the replay attack.The computation cost of this scheme is very low. 关 键 词：远程验证 混乱信息函数 智能卡 服务器 用复验证
