为解决无线Mesh网络节点高效、安全入网认证的问题,提出了一种新的基于标识认证的无线Mesh网络接入认证协议.该协议针对无线Mesh网络的特点,将标识认证体制引入到无线Mesh节点接入认证当中,并在标识认证的基础上一次性完成了入网节点的双向身份认证、网络认证和空口密钥的建立3个步骤.简化了认证的流程,减少了认证的时延,达到了分布式认证的效果,为大规模的节点接入提供了一种新的认证方案.通过BAN逻辑形式化方法证明了协议的安全性,通过效率分析说明了协议的高效性.%To deal with efficiently and safely access for wireless mesh network (WMN), a new wireless mesh network access au thentication protocol using identity-based cryptography is proposed. By taking WMN factors such as no-center, adaptive, multi hop into consideration, identity-based authentication mechanism is introduced into WMN access authentication, based on which two-way Identity confirmation, network authentication and key agreement between accessing-node and accessed node are finished. According to the protocol, the process of authentication is simplified, and the delay of authentication is also reduced, meanwhile, distributed authentication is realized, last and most important, a new authentication method is provided to mass node access. In the end, security is proved by the method of BAN logic formal verification, and the efficiency is shown by efficiency analysis.
