摘要: 为解决大规模异构无线传感器网络组密钥更新能耗大、效率低的问题,提出一种基于拓扑信息的异构无线传感器网络组密钥管理方案。利用节点拓扑信息构建αβ密钥管理树,在密钥管理树的生成与更新过程中对其进行结构优化,从而减少组密钥更新的能量消耗与更新时延。仿真实验表明,该方案是一种高效可扩展的组密钥管理方案,适合应用于异构无线传感器网络中。

Abstract: To solve the great energy cost and poor efficiency of group key updating in Heterogeneous Wireless Sensor Network(HWSN), this paper proposes a group key management scheme based on topological information for HWSN. The scheme takes topological information of nodes to build an αβ key management tree. In the process of generating and updating, the group key management tree must be optimized to decrease energy cost and updating delay. Simulation experiments show that the scheme is an efficient and scalable group key management scheme which is suitable for heterogeneous Wireless Sensor Network(WSN).

Key words: Heterogeneous Wireless Sensor Network(HWSN), group key updating, topological tree, key management tree
