基于矩阵空间的高效密钥管理方案

摘要

In order to enhance the connectivity and security of Wireless Sensor Network (WSN), and to reduce the energy consumption of transmission, this paper proposed a key protocol using matrix space and deployment. This protocol partitioned the space for corresponding to the sub-matrix by deployment and adjusted the distance of the sub-space to ensure the connectivity of network. The theoretical studies and simulation show that connectivity can be up to 100 percent by setting reasonable parameter of sub-matrix space, and the efficiency of communication and computation and the safety of the network can be effectively improved.%为了增强无线传感器网络的安全性与连通性,同时进一步减少传输能量消耗,提出一种基于矩阵空间和部署信息的密钥协议.该协议利用部署策略对网络进行合理的分区,并将分区与子矩阵空间逐一对应,通过调整子矩阵空间的距离保证网络的连通性.理论分析和仿真结果表明,通过设置合理的子矩阵空间参数,不仅保证网络100％的连通率,而且有效地提高节点的通信效率和计算效率,提高了无线传感器网络节点的抗捕获攻击能力.
