摘　　要：作为Ad hoc网络大规模应用的先决条件,安全问题必须得到解决。为了加强对中间节点的安全评估以及对多路径路由的保护,本文提出一种基于攻击因子AF(Attacking Factor)的多路径安全路由机制,引入能够衡量节点当前及未来遭受攻击的可能性的攻击因子以评估多路径集的安全性,并在此基础上实现了链路安全预警,降低了恶意攻击带来的损失。仿真结果表明,在不安全的网络环境下,本文机制有效保护了路由控制消息,提高了多路径路由建立的效率。As a prerequisite for broad application of Ad hoc network,security problem must be solved. To enhance the security evaluation of intermediate nodes and the protection of multipath routes, we present a secure multipath routing mechanism based on Attacking Factor（AF）, which can indicate the possibility of being attacked currently and in the future. AF can be used to evaluate the security of multipath sets, then link security alarming can be implemented to reduce the loss from malicious attack. The simulation results show that this mechanism can protect routing control message effectively and improve the efficiency of multipath routing establishment in unstable environment.
