摘要: 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。

Abstract: 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.
