| 摘 要： | 对标准模型下可证安全的基于身份认证密钥协商协议进行安全分析，指出由于传送消息存在冗余，协议不能抵御伪装攻击。为解决上述安全漏洞，提出一个改进的基于身份认证密钥协商协议，并在标准模型下分析其安全性。结果表明，新协议满足基于身份认证密钥协商协议的所有安全要求。

| Abstract: | Analyzed the security of a recently proposed ID-based authenticated key exchange protocol without random oracles,it was shown that the protocol suffer from impersonation attacks due to redundancy of the exchange messages. To overcome this problem,presented an improved version of the protocol and gave security analyses in the standard model. Results show that it satisfies all the security requirements of an ID-based authenticated key exchange protocol. |
