This greatly reduces the computation overheads. Security Association Routing Protocol (SARP) can be applied as an extension of DSR (Dynamic Source Routing) in a natural way.

• 基于安全关联的安全路由协议SARP(Security Association Routing Protocol)可以方便地在DSR(Dynamic Source Routing)路由协议上扩展,它要求需要进行安全通信的两个节点之间存在一个安全关联。
