一种简单的密码认证密钥交换协议

Pretty-Simple Password-Authenticated Key-Exchange Protocol

Kazukuni Kobara, Hideki Imai

摘要:

基于DDH问题求解的困难性,我们提出了一个非常简单的密码认证密钥交换协议。该协议具有以下优点:(1)协议中的$y_1$和$y_2$是独立的,因此它们可以预先计算并独立发送。这加快了协议的速度。(2)客户端和服务器可以使用几乎相同的算法。这降低了实施成本,而不会接受重放攻击和滥用实体作为预言机。

英文摘要:

We propose pretty simple password-authenticated key-exchange protocol which is based on the difficulty of solving DDH problem. It has the following advantages: (1) Both $y_1$ and $y_2$ in our protocol are independent and thus they can be pre-computed and can be sent independently. This speeds up the protocol. (2) Clients and servers can use almost the same algorithm. This reduces the implementation costs without accepting replay attacks and abuse of entities as oracles.
