摘要
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.
Key management is one of the key security technology in wireless sensor networks.Key management in wireless sensor networks due to the arrangement of the position,limited the calculation,limited storage capacity,makes the designer faces many challenges;so a key-management scheme based on identity and cluster layer for wireless sensor network is proposed.The scheme uses identity authentication and encryption technology to carry out the cluster node authentication and key negotiation to resolve the problem within the cluster,namely the establishment of a shared cluster key among cluster members and cluster head.By security analysis,complex analysis,performance analysis,and compared with other programs,programs can ensure full connectivity within a cluster,the new node and easy to join,so as to meet the requirements of wireless sensor networks.
