摘　　要：Ad hoc网络的开放性、自组织、可移动等特点使其路由的安全问题日益突出,然而,目前大多数的路由协议并没有考虑该问题.文章给出了一种基于DSR的安全多径路由协议(SMDSR),该协议采用简单易实现的独立多径路由算法,并通过信任机制和公钥密码体制使其能有效地抑制伪装、篡改和路由重放等典型的安全攻击.模拟实验结果表明SMDSR路由协议的路由性能要优于DSR,并具有良好的安全性.The openness, self-organizing and mobile of Ad hoc networks make the routing security an important issue. However, most of the existing routing protocols don＇ t take this security problem into account. This paper proposes a secure multipath routing pro- tocol based on DSR, which uses a simple independent multipath routing algorithm, trust mechanism and public key cryptosystem, as a result ,this routing prot^ol is capable of effectively restraining several typical security attacks such as fabrication, modification and muting reply. The results of experiment show that the SMDSR routing protocol provides better routing performance and higher security than DSR.
