| 摘 要： | 在Shim(2003)的基于证书的三方密钥协商协议的基础上提出了一个基于对的组密钥协商协议。通过在密钥生成函数中引入伪随机数，防止了未知密钥共享攻击(the unknown key-share attack)和已知密钥攻击。给出了当前文献中已知的一些攻击方法，并证明这些攻击方法在此协议中是无效的。同时此协议具有前向安全和后向安全的特性，即在动态组的情况下协议仍是安全的。

| Abstract: | This paper proposes a pairing-based group key agreement protocol based on Shim's certification-based tripartite key agreement protocol. This protocol adopts a pseudo-random sequence to avoid the unknown key-share attack and the known-key attack. Some attacks described in the literatures are presented, which proved infeasible in the protocol. And this protocol can achieves the forward security and backward security, when a dynamic group performs it. |
