【摘要】 在无线传感器网络中,安全问题越来越受到人们的重视,而密钥预分发方案是传感器网络的安全基础。本文结合节点的位置信息,提出了一种基于正六边形的密钥预分发方案。该方案在进行节点间密钥分发时,充分利用节点的位置信息,通过构造一个正六边形部署模型来优化密钥分发过程。分析及仿真结果表明,和现有的基于位置信息的密钥预分发方案相比,该方案可以提高网络的安全连通性,并能较大程度地增强网络的抗攻击能力。更多还原

【Abstract】 In wireless sensor networks,people attach more importance to the problem of security,and key pre-distribution scheme is the foundation of WSN security.According to the idea of taking advantage of the location information of nodes,this paper presents a key distribution scheme based on the hexagon model,which optimize the process of key pre-distribution by constructing a hexagon deployment model.The analysis and simulation result show that this scheme can improve network security connectivity,and can enhance the anti-attack ability of the network to a great extent.更多还原
