无线传感器网络的密钥管理由于布置位置、计算量和存储能力受限,使得设计时需要进行诸多考虑.为此,提出了一种基于身份的无线传感器网络层簇式密钥管理方案,可以较好地解决无线传感器网络的密钥管理问题.本方案运用身份认证加密技术,对节点认证后进行分簇,并解决簇内密钥协商问题,即建立簇成员与簇头之间共享簇密钥.通过安全性、复杂性分析和效能分析,并与一些常用方案进行对比,验证了本方案可以保证簇内完全连通、新节点便捷加入,能够满足无线传感器网络各项要求.
Because of the location of the key, the limited amount of computation and storage, the key management of WSN needs to be considered in the design time.Therefore, an identity-based wireless sensor network cluster key management scheme is proposed, which can compare So as to solve the problem of key management in wireless sensor network.This scheme uses the authentication technology of encryption to cluster nodes after authentication and solve the key agreement problem in the cluster, that is, to establish the shared cluster key between cluster members and cluster heads Through the analysis of security, complexity and performance, and compared with some common schemes, it is verified that this scheme can guarantee the complete connectivity within the cluster and the new nodes can be easily added to meet the requirements of wireless sensor networks.
