无线传感器网络的组密钥更新算法

Group rekeying algorithm in wireless sensor networks

提出了一种适用于无线传感器网络的基于改进密钥链接树的组密钥更新算法。通过在基于密钥链接树的组密钥管理方案中引入问题密钥路径,并延迟这些问题密钥路径上的密钥更新操作,从而减少密钥链接树中辅助节点上的重复密钥更新。实验结果表明,与现有的组密钥管理方案相比,基于改进密钥链接树的组密钥更新算法在节点添加和删除操作时产生更少的密钥更新消息和消耗更少的能量。

This paper proposed a refined key link-tree based group rekeying algorithm that is suitable for wireless sensor networks. By incorporating problem key paths into the key link tree-based group key management scheme and delaying the key update operations in problem key paths, the number of duplicate key update messages for auxiliary nodes could be reduced. The experimental results show the algorithm requires fewer rekeying messages and costs less power in the node adding and deleting operations than the existing group key management schemes.
