一种基于双线性配对的移动自组网密钥协商协议

移动自组网是一种无固定网络基础设施、能量和计算资源有限的分布式动态网络,由于其无线传输链路的开放性,使得它非常需要一种计算和通信开销较小的密钥协商方案.本文基于椭圆曲线上双线性配对的概念,提出了一种适用于移动自组网的可认证密钥协商方案,既实现了邻居节点组成员身份认证的匿名性,也实现了需建立会话的节点之间的可认证密钥协商.分析表明,我们所提出的方案计算和通信开销比较小,安全性较好,非常适合于资源有限的移动自组网.

A Bilinear Pairing-based Key Agreement Protocol in MANET

As a new type of dynamic infrastructure-less networks,mobile Ad Hoc networks are vulnerable to many types of attacks.So the key agreement protocol with mutual authentication between communicators is crucial for the security of MANETs.A key agreement scheme with mutual authentication,which is based on bilinear pairing,is proposed in this paper.This scheme implements two key agreement protocols.One is for the anonymous group member authentication among neighbors.The other is for the session key agreement with mutual authentication.The security and computation cost are analyzed.The results show that the scheme proposed in this paper is very suitable for MANETs.
