| 摘 要： | 大多数的认证密钥协商协议没有考虑用户的匿名性，在分析已有MAKAP协议的基础上，提出了一种具有用户匿名性的认证密钥协商协议AKAPA，为用户提供隐私保护。在随机预言机模型下证明其安全性，并就增强的安全属性进行了分析，表明AKAPA具有完美前向安全性，能够抗未知共享密钥攻击和完善拒绝服务攻击等。性能分析表明效率优于已有协议，具有较高的实用性。

| Abstract: | Most of the existing authenticated key agreement protocols are not designed for anonymity of user. Based on mutually authenticated key agreement protocols(MAKAP),this paper proposed a new AKAPA, which protected privacy of user. Proved the security of the protocols in ROM, and then enhanced security properties, such as perfect forward secrecy,also analyzed unknown key share and perfected denial of service. Moreover, analyzed performance of AKAPA. And the result shows that the protocol is more efficient, so it is quite practical. |
