基于无线传感器网络的一种安全路由协议

A Secure Routing Protocol for Wireless Sensor Networks

针对无线传感器网络(WSN)中路由协议的安全隐患,提出了一种安全的路由协议.该路由协议在传统的定向扩散协议基础上增加安全机制,把整个路由过程分为路由建立和路由更新2个阶段,并对其安全性进行分析.通过在路由建立阶段使用小区密钥和通信密钥,能为网络选择安全的路由;路由更新能在出现路由故障时重新建立路由,进一步提高了无线传感器网络的路由安全性能.

To the problems of less consideration of security requirements in wireless sensor networks, the secure routing protocol is presented. Based on the traditional direct diffusion protocol （DD） , the security mechanism is added into it. The routing process is divided into two steps： routing set-up and routing update. The security performance is analysed. In the first step the region and communication keys are used to select security routings for the WSN, and in the second step the routing updating can make the fault lines resume the new routing, which enhances the routing security performance of the WSN.
