摘　　要：针对无线传感器网络随机密钥预分配方案和基于部署信息的密钥管理方案的不足,提出了一种新的基于六边形网格部署理论的无线传感器网络随机密钥预分配方案。将网络分成两种类型的六边形网格,不同网格内的节点采用不同的方式建立密钥,通过结合节点部署理论和组合设计理论,有效地提高了网络抵御敌手攻击的能力。理论分析和模拟结果表明,该方案相较于其它方案具有更高的连通率和网络安全性。Key management is the foundation for the secure communication in wireless sensor networks. A novel key pre-distri- bution scheme based on deployment knowledge is proposed. In this scheme, the target field is divided into two kinds of hexagons grids ： group grids and key grids. Nodes in group grids and key grids are treated differently. By combining deployment knowledge with combinatorial approach, this scheme can drastically reduce the fraction of compromised links when some nodes are captured while maintaining a high connectivity. The simulation results show that the proposed scheme performs better in terms of resi- lience against node capture compared with other existing schemes.
