| 摘 要： | 口令认证密钥交换（PAKE）协议由于其便于记忆、运行成本低等特点受到广泛关注。文章在百万富翁协议算法的基础上，通过简化和改进，提出一种口令认证的密钥交换协议。该协议使用一个低熵的口令进行双方的认证，并得到一个高熵的密钥。文章同时分析了该协议对抵御中间人攻击和离线字典攻击的安全性。

| Abstract: | Password authentication key exchange （PAKE） protocol is widely concerned about due to its low cost and ease of memory. Through simplifying and improving a millionaire＇s protocol, this paper proposes a password authentication key exchange protocol. The protocol can get a high entropy key by authenticating through a low entropy password. This paper also analyzes the protocol＇s security of resisting man-in-the-middle and ottline dictionary attacks. |
