一种双簇头无线传感器网络密钥管理方案探索

Exploration of a Key Management Scheme for Double Cluster Head Wireless Sensor Networks

密钥安全和节点能量受限是无线传感器网络中密钥管理要考虑的问题。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项散列函数,给出一种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。性能分析结果表明:该方案能够保证节点的高连同率和强抗捕获性,较低的存储开销和通信能耗开销,以及良好的可扩展性,可在实际的网络环境中广泛应用。

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 wireless sensor networks 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.The performance analysis results show that the scheme can ensure the node’s high rate of integration and strong anti-capture,low storage and communication energy consumption,and good scalability,and can be widely used in the actual network environment.
