摘　　要：针对异构无线传感器网络中密钥管理方案中的安全连通性差、节点抗攻击能力不强、存储开销大等问题,采用了一种基于节点分组部署的异构无线传感器网络密钥管理的方案.该方案将部署区域划分为六边形分组,对各个分组分别部署密钥,以提高节点的安全连通率;不同分组区域内节点存在共享密钥概率减小,增强节点的抗捕获能力;簇头节点之间共享密钥建立采用Hadamard矩阵密钥预分配方案,使相同存储开销下,任意两个簇头节点之间都存在共享密钥,以实现安全通信.通过仿真实验表明,本文方案能够有效提高节点的安全连通率,增强节点的抗捕获能力,减小存储开销.To solve the problem of low security connectivity,the less ability of resilience to the node capture attacks and higher storage overhead,this paper proposes a key management based on node grouping deployment for heterogeneous wireless sensor networks. In order to enhance the ability of resilience to the node capture attacks,the deployment area is divided into hexagon groups,and each group is distributed keys respectively to improve the secure connectivity of the nodes and reduce the key sharing probability in different groups. In head sensors sharing key establishment,Hadamard matrix key pre-distribution scheme is used to make sure any two head sensor has a shared key to realize secure communication under the same storage overhead. Through the experimental simulation and performance analysis,the scheme of this paper can improve node security connectivity effectively,and enhance the ability of resilience to the node capture attacks and decrease storage overhead.
