无线mesh网络的特性使它面临着比传统无线网络更大的安全挑战.其安全解决方案必须兼顾安全性和应用环境等因素.用户节点的接入认证与密钥协商是节点漫游时最基本的安全协议,是安全路由等协议的实现基础.在多跳车载mesh网络用户节点接入认证中,用户身份信息的保护非常重要,然而有关车载mesh网络用户节点漫游时的匿名认证的研究较少,为此,在充分考虑无线mesh网络自身特点的基础上,结合基于Hash和Diffie-Hellman算法,提出一种高效的用户节点匿名接入认证与密钥协商协议.分析发现,该协议不仅可以满足安全性需求,在现实应用中也是可行的.

Due to their own eharacteristics,wireless mesh networks are facing more security challenges than traditional networks.Their security mechanism should take into account both the security and the application environment.Anonymous authentication and key negotiation,when users roam,are an elementary protocol in constructing a secure network system,and are the implementation foundation of the Secure routing protocol.The user's certificated in wireless mesh networks,protection of identity information is very important,but the study of anonymous authentication and key negotiation when users roam in wireless mesh networks was too little.Motivated by these concerns,on the enough consideration on the attack methods for wireless networks and the characteristics of wireless mesh networks,an efficient roaming authentication with anonymity protocol for wireless vehicle mesh networks was proposed.in which the ID based public key cryptography and Diffie-Hellman algorithm were adopted.Analysis shows that this protocol can be used to guarantee the security of wireless mesh networks,and at the same time,it can meet the special application environment of wireless vehicle mesh networks.
