基于IBC的无线传感器网络层簇式密钥管理方案

Key-management Scheme Based on IBC for Clustering Wireless Sensor Network

密钥管理是无线传感器网络中关键安全技术之一。无线传感器网络的密钥管理由于布置位置、计算量有限、存储能力有限,使得设计面临许多挑战。在分析无线传感器网络安全需求的基础上,针对无线传感器网络密钥管理问题,运用层簇式网络结构,通过身份加密方式,进行节点合法性认证,完成基站与簇头,簇头与节点之间的密钥,保证无线传感器网络安全通信。通过安全性分析和效能分析,该密钥管理方案较好的满足无线传感器网络的安全需求,降低通信开销,有效地解决密钥管理的问题。

Key management is one of the key security technology in wireless sensor networks. The key management of wireless sensor network because the arrangement widely, calculation, storage capacity is limited, which makes the design fa- cing a lot of challenges. Based on the analysis of the security requirements of wireless sensor networks, aiming at the key management problem in wireless sensor networks, application layer cluster network structure, the identity based encryption method, node legitimacy authentication, the paper complete key management of the base station and cluster head and between the cluster head and the node key, to ensure the safety of communication in wireless sensor network. Through the analysis of security and performance, the key management scheme satisfies the security requirements of wireless sensor network, reduce the communication cost, solve the effective key management problems.
