摘　　要：移动ad hoc网络无中心、拓扑结构动态变化等特点,以及节点能源和计算能力有限,使其安全路由设计面临巨大挑战.在按需路由的基础上提出了一种多路径安全路由算法,采用高效的分布式密钥管理策略,路由过程中隐藏通信节点的地址信息,节点之间逐跳认证保证信息的完整性,能够抵御单路径协议不能抵抗的多恶意节点的合谋攻击,同时能平衡负载,具有更好的安全性能和网络性能.Because ad hoc network whose nodes has finity energy and low ability is without infrastructure and has dynamic topology, it is a big challenge to design security routing for it. In this paper, an ad hoc multipath security routing algorithm is proposed based on on-demand routing, which uses efficient distributed agreement protocol. It can hide the information of node's address and authenticate hop by hop and check the integrity of information. It can resist security attacks of collaborating malicious nodes and balance the load. It has better security and high efficiency.
