无线传感器网络中基于IBE算法的组密钥管理方案

摘要

There are no long-term credibility of the nodes, unreliable links and limitations of resources in wireless sensor networks as that in traditional networks. Based on cluster structure of WSN and identity-based encryption, this paper proposed a novel group key management scheme for WSN, which verified the correctness of group key shares, ensured the generation and rekeying of the group key and provides secure group communications. Extensive analyses and simulations show that the proposed scheme can provide a high level of security, reduce communication and storage overheads.%针对无线传感器网络无长期可信的节点、信道可靠性差及其资源十分有限等特点,基于无线传感器网络的簇结构和IBE算法提出一种新的组密钥管理方案,能够验证组密钥分量的正确性,确保组密钥的正确生成和更新,提供安全的组通信.理论分析及仿真结果表明,新方案具有很高的安全性,以及较小的存储开销与通信开销.
