针对无线网络中路由协议的安全问题进行研究,分析了LEACH协议可能受到的攻击,并提出了一种安全的LEACH协议(SLEACH),引入了节点间的安全认证方案,对该方案通过BAN逻辑语言进行了证明。通过信誉机制遏制内部异常节点的自私行为。仿真结果显示,SLEACH在性能上的影响是可以接受的。
This paper analyzed the wireless network secure problem and proposed a secure LEACH routing protocol. It induced the secure authentication and used the BAN proving it. The reputation mechanism ensured that the selfish node would abide the protocol. The result of simulation shows that SLEACH has the acceptable affect.
