摘　　要：目前无线传感器网络路由协议的研究多以网络生存时间为目标,缺乏对路由安全的考虑。分析了无线传感器网络路由协议容易受到的攻击形式,研究了典型的分簇路由协议LEACH(Low-Energy Adaptive Clustering Hierarchy)协议存在的安全隐患,并提出改进的安全LEACH(LEACH-S1)协议。改进后的算法通过三重安全机制、节点定位技术、动态随机多路径簇头链的建立不仅有效地避免了恶意节点的攻击,保障了路由安全,而且延长了网络生存时间。At present, most routing protocols in wireless sensor networks take the survival time of network as their design target, and don＇t take security into consideration. The paper analyzes several classes of at- tacks against wireless sensor networks , makes a research on the security of LEACH and proposes an im- proved algorithm--Secure LEACH（LEACH-S1）. The improved algorithm can not only avoid the attacks of adversary effectively, ensure the routing security , but also balance the power consumption over all nodes , prolong the lifetime of the network via using tripartite security mechanism, node localization technology and dynamic stochastic multi-paths cluster heads chain.
