摘　　要：分析无线传感器网络中密钥管理和分簇路由协议存在的安全漏洞,利用模糊推理系统,将簇头与簇内节点的共享密钥数作为重要评判指标,建立一种基于密钥连通的簇头选择安全算法。不同于传统的模糊推理算法,该算法实现了分簇路由协议与密钥管理方案的良好结合,与典型分簇算法相比,能有效降低并均衡簇内的通信能耗、增强通信安全。The security leakage of current key management scheme and clustering routing protocols in Wireless Sensor Networks（WSN） is analyzed,and a cluster head selection algorithm based on key connection is proposed.It takes the number of keys shared between cluster head and cluster nodes as the important index,using the fuzzy inference system.Unlike to the traditional fuzzy inference algorithm,the algorithm achieves a good combination between the clustering routing protocols and key management schemes,effectively lowering and balancing the communication energy in a cluster and improving the communication security compared with the typical clustering algorithm.
