摘要: 为满足无线传感器网络的高安全性要求,提出基于树型结构的无线传感器网络动态密钥管理方案。采用MAC机制与节点唯一ID相结合的认证方法和逻辑树型密钥池,利用平衡二叉树实现动态密钥更新。实验结果表明,与原有方案相比,该方案的计算能耗和通信能耗均较小。

Abstract: To meet the high security needs of WSN, this paper proposes WSN dynamic key management scheme based on tree structure. MAC mechanism and unique ID method are combined. Logic tree key pool is used. Dynamic key update is realized by balance binary tree. Experimental results show that compared with existing schemes, this scheme needs littler energy consumption for computation and communication.

Key words: network security, WSN, dynamic key management, tree structure
