分层无线传感器网络密钥管理研究

Hierarchical Key Management in Wireless Sensor Networks

随着无线传感器网络规模日渐扩大,层次拓扑结构正成为主导。为此,文中提出了一种适用于分层无线传感器网络的多密钥空间q复合密钥预分配方案。通过安全连通性和节点抗捕获性分析表明该方案可在保证节点间安全连通概率的基础上,提高网络的安全阈值,提升网络的抗攻击能力,增加网络安全性。

With the widening scale of wireless sensor networks,hierarchical topology is becoming dominant.Therefor,this paper proposes a multi-key space q-composite key pre-distribution scheme for hierarchical wireless sensor networks.The performance analysis by secure connection between nodes and nodes resist captured probability show that this scheme can increase the threshold of captured nodes,which is better resilient against attack,and improve the security of network..
