摘要: 针对传感器网络中无长期可信节点的特点,基于传感器网络的簇结构和门限密钥共享机制提出一种新的组密钥管理方案,使得只有组中的合法节点才能存储一个有效的组密钥分量。组密钥更新时,组密钥由节点协同产生并由簇头安全分发。理论分析和仿真实验表明,该方案具有良好的安全性,在组密钥更新时存储开销和通信开销较低。

Abstract: There are no trust nodes in sensor networks as that in traditional networks. Based on cluster structure of sensor networks and threshold secret sharing mechanism, a novel group key management scheme for sensor networks is proposed in this paper, in which only innocent nodes have an efficient group key share. When group is rekeying, multiple entities in a local neighborhood can jointly create a new group key to be distributed by cluster heads securely. Analysis and simulations show that the scheme has lower memory and communication overheads besides good security performance.

Key words: sensor networks, cluster structure, threshold secret sharing mechanism, group key management
