摘要: 针对层次型无线传感网络(HSN)中的安全通信问题,提出了一种基于逻辑密钥树(LKH++)的组密钥管理方案——W-LKH++。针对无线传感器节点的低配置特点,首先,对LKH++树的组密钥初始化计算方法进行修改,降低传感器节点的计算消耗;其次,对LKH++的组密钥持有方式进行改进,减少传感节点的存储消耗;最后,提出适用于簇头节点的动态密钥更新方法,在降低通信消耗的基础上增强簇头节点的抗捕获能力,提高无线通信网络的安全性。性能分析和仿真实验结果表明,W-LKH++在保证低计算、存储和通信消耗的基础上,进一步提高了网络安全性。

Abstract: Aiming at the security communication problem of Heterogeneous Sensor Network (HSN), a secure group key management scheme W-LKH++ was proposed based on LKH++ tree. Firstly, as the wireless sensor nodes with low configuration, the initialization method for group key of LKH++ tree was modified to reduce the computationol overhead on each sensor node. Then, the holding way of keys were improved to reduce the storage overhead on each sensor node. Finally, a dynamic key updating method suitable for cluster head nodes was proposed to enhance the ability against node capture of the cluster head nodes based on low communication overhead, improving the security of communication of Wireless Sensor Network (WSN). Performance analysis and simulation results show that W-LKH++ improves the WSN security with low computation, storage and communication overhead.

Key words: Heterogeneous Sensor Network (HSN), group key, Wireless Sensor Network (WSN), key tree, key management
