无线传感器网络中,路由算法是否安全直接影响整个网络的安全性和可用性。所以,基于LEACH路由协议,通过增加身份认证机制、密钥的动态更新机制,以及双重密钥加密机制,提出了一个新的安全策略——IS-LEACH,并给出了该策略的详细设计和分析
The security of the routing protocol of Wireless Sensor Network(WSN) has direct influence on the security and availability of the entire network.By adding identity authentication mechanism,key update mechanism and dual-key encryption mechanism to Low Energy Adaptive Clustering Hierarchy(LEACH) protocol,a new secure LEACH protocol—— IS-LEACH is proposed.Detailed design and analysis of the proposed protocol are given.
