摘　　要：无线传感网络安全性在很大程度上依赖簇首,对该节点的维护和分配对其安全性具有重要意义。为此,基于混合密钥分配提出了一种无线传感网络安全分簇方法。该方法在建立无线传感网络模型和攻击者模型的基础上,根据赋权能力将无线传感网络节点分为高级节点和普通节点,并利用混合密钥分配技术,分别提升两类节点的安全性能。通过将节点映射至粒子传感器的工作区域内,实现无线传感网络安全分簇。测试结果表明,所提方法“死亡节点”留存时间低于0.2 s,数据包传输总量高于900 bit。The security of wireless sensor networks depends on the cluster head to a large extent.The maintenance and allocation of this node is of great significance to its security.Therefore,a secure clustering method for wireless sensor networks based on hybrid key distribution is proposed.Based on the establishment of the mathematical model and the attacker model of wireless sensor network,the wireless sensor network nodes are divided into advanced nodes and ordinary nodes according to the weighting ability,and the hybrid key distribution technology is used to improve the security performance of the two types of nodes.By mapping the nodes to the working area of the particle sensor,the secure clustering of wireless sensor networks is realized.The test results show that the"dead node"retention time of the proposed method is less than 0.2 s,and the total packet transmission is more than 900 bits.
