摘　　要：密钥安全与节点能量受限是无线传感器网络密钥管理中要同时考虑的问题。为有效改善节点密钥存储开销和通信能耗开销,通过结合圆锥曲线密码和单向散列函数,给出一种基于圆锥曲线密码的双簇头无线传感器网络密钥管理方案。该方案中主簇头节点负责安全收集和簇内节点的数据传输,副簇头节点则负责簇内密钥管理工作。由性能分析结果可知:该方案能保证节点的高连同率与强抗捕获性,较低的存储开销与通信能耗开销,以及良好的可扩展性,可较好地应用在实际的无线传感器网络环境中。The security of key and the limited energy of nodes should be considered in key management of wireless sensor networks simultaneity.In order to improve the consumption of key storage and communication energy,a key management scheme of dual cluster heads for WSNs based on conic curve cryptography was proposed by combining conic curve cryptography and Hash functions.The main cluster heads were responsible for safely collecting and transmitting the data information,and the assistant cluster heads take charge of the key management of the nodes.Performance analysis results demonstrate that the novel scheme could ensure the high connectivity rates,the strong anti-capture ability,the low key storage consumption,the low communication energy consumption and the fine extendibility.Thus the novel scheme could be used the actual environment of wireless sensor networks.
