移动Ad Hoc网络可认证安全匿名通信研究

传统的移动Ad Hoc网络匿名路由协议无法鉴别伪造的路由控制分组,并且公钥运算过多导致路由建立时间延长.提出一种基于邻居认证的安全匿名路由协议以解决上述问题,通过基于临时身份公钥的邻居匿名认证机制鉴定邻居节点合法性并动态协商密钥,路由发现过程中利用邻居协商密钥对路由控制消息进行逐跳的验证与处理.上述机制使得伪造路由分组可被有效鉴别,并且中间节点基于对称密钥运算处理分组降低了路由发现时延.理论分析和仿真结果表明,该协议可对抗基于伪造分组的DoS攻击,并且较传统协议具有更低的路由建立时间.

Research on Anonymous and Authentic Communications in Mobile Ad Hoc Networks

In traditional anonymous routing protocols in mobile Ad Hoc networks,forged route control packets can't be distinguished and too many public key operations make the route construction delay too long.A new secure anonymous routing protocol based on neighborhood authentications was proposed to solve such problems.By anonymous neighborhood authentications using temporary identity-based public key,shared keys were established between legal neighboring nodes.In anonymous route discovery process,route control pac...
