基于六边形网格部署模型的传感器网络密钥管理

在未知和敌对环境中,密钥管理是传感器网络安全的一个基本组成部分.本文提出了一种新的基于六边形网络部署模型的传感器网络密钥管理方案.该方案综合了Blom方案和节点部署知识的特点,把整个传感器网络划分为若干个互不重叠的六边形单元格,并在邻近的单元格应用Blom算法.分析和仿真结果显示:利用节点部署知识,网络连通概率保持了较高的水平;另一方面,通过引用Blom算法,方案在减少存储容量消耗的情况下提高了节点抗捕获攻击能力.

Key Management in Sensor Network Based on Hexagon Grid Deployment Model

Key management is a fundamental building block for securing sensor networks deployed in unattended and hostile environments. In this paper, we propose a new key management scheme based on hexagon grid deployment model by combining Blom's scheme and node deployment knowledge. In the proposed scheme, the entire sensor network is divided into several non-overlapping hexagon cells, and Blom's scheme is applied in each pair of neighboring cells. Analysis and simulation results show that using node deployment kno...
