摘要
文章提出了一种基于伪随机数生成器的无线传感器网络密钥预分配方案。该方案是概率性的,具有高连通概率、捕获少量节点时低损伤概率的特点。同时,具有良好的性能和抵抗复制节点攻击。
In this paper, a PRNG-based key pre-distribution scheme for WSN is proposed. The scheme is probabilistic, with high safety connected probability and low fail probability when small mount of nodes are captured. Moreover, it performs well and resist to node copying attack.
