| 摘 要： | 对Wang等提出的一种基于身份可认证的密钥协商协议进行协议安全性分析后发现，该协议存在安全性不足，如存在冗余信息、假冒攻击和临时秘密信息泄漏攻击。为解决这个问题，对该协议进行了改进，并对改进后协议的安全属性和运行效率进行了分析。分析结果表明，改进后的基于身份可认证的密钥协商协议满足已知所有的密钥协商协议的安全属性要求，且拥有可靠的效率。

| Abstract: | The security of an ID-based authentication key agreement protocol proposed by Wang et al was analyzed.The security flaws such as redundant information,impersonation attacks and temporary secret information leakage attacks werr pointed out.To overcome these security flaws,an improved protocol was proposed base on the original protocol.And the security and the operating efficient of the improved protocol were also analyzed.It was showed that the improved ID-based authenticated key agreement protocol can satis... |
