发布时间：2018-08-22 12:05
【摘要】：提出一种传感器网络多密钥空间分层密钥预分配方案。该方案把部署区域划分为正六边形网格,将节点分成不同的簇,密钥空间划分为与簇相对应的子集;簇头节点之间采用多密钥空间随机预分配方案进行共享密钥发现,簇头节点与普通节点间则采用单项散列计算的方式计算共享密钥。性能分析和仿真结果表明,该方案在连通率及抗捕获攻击方面有较好的性能改善,通信和存储开销预算较合理。
[Abstract]:A multi-key space hierarchical key pre-distribution scheme for sensor networks is proposed. In this scheme, the deployment area is divided into hexagonal grid, nodes are divided into different clusters, and the key space is divided into corresponding subsets. The shared key is calculated by single hash between cluster head node and common node. The performance analysis and simulation results show that the proposed scheme has better performance improvement in connectivity and anti-capture attack, and the budget of communication and storage overhead is reasonable.
