摘要： 在无线网络的分布式环境中，通信双方间建立安全的会话很重要。在借鉴以往无线通信密钥协商协议的基础上，提出一个在对称实体之间可相互认证的密钥协商协议SAKAP，在随机预言机模型下证明其安全性，并给出协议的性能分析。与以往的协议相比，该协议是可证明安全的，且具有较高的可行性。

Abstract: In the distributed computing environments such as wireless network, it is critical to establish a secure session between communicators. A mutual key agreement protocol, namely Symmetrical Authenticated Key Agreement Protocol(SAKAP), is proposed to authenticate identities and establish secure session key between symmetrical users. The security of the protocol is proved in Random Oracle(RO) model, and its performances are analyzed. SAKAP has the advantages of provable security and considerable feasibility over other protocols.

Key words: authenticated key agreement protocol, provable security, Random Oracle(RO) model
