一种安全的LEACH路由算法

Secure Routing Algorithm of Low Energy Adaptive Clustering Hierarchy

在研究低功耗自适应集簇分层型路由协议的基础上,从路由安全的攻防角度入手,分析现有各种路由攻击手段的原理、特点及危害,提出一种基于身份认证的密钥协商安全防范密钥管理对策,同时利用秘密共享技术防范关键点攻击,为无线传感器网络安全路由的设计与实现提供一个可行的方案。

Based on the analysis of the routing protocol of Low Energy Adaptive Clustering Hierarchy（LEACH）, it starts to the view of the offensive and defensive in the routing security, expatiates the existing principle of the routing attack detailedly, and proposes a key management of key agreement based on identification authentication to keep away the attack. At the same time, it uses the secret sharing techniques to prevent key points attacking, also provides a proposal tosecure routing of WSN on the design and implementation.
