分析了Email蠕虫与传统蠕虫在扩散传播行为上的不同,着重研究了网络拓扑结构对Email蠕虫传播行为的影响,通过对powerlaw网络模型,小世界(smallworld)拓扑模型和随机拓扑模型三种网络结构的分析设计与仿真实验,提出了Email蠕虫在powerlaw拓扑模型传播速度最快并且易于感染高连接度节点的结论。 The difference between Email worm and traditional worm in diffusion spread behavior is analyzed. The influence of network topology on Email worm propagation is analyzed emphatically. By analyzing the powerlaw network model, the smallworld topology model and the stochastic topology model Analysis and design of simulation experiments, the conclusion that Email worm has the fastest propagation speed in powerlaw topology model and is easy to infect highly-connected nodes is proposed.
