摘要
概述了当前几种常用的蠕虫病毒传播模型,具体分析了随着因特网体系结构的演化,网络中NAT等设施的出现对蠕虫病毒传播带来的影响。针对传统模型在描述病毒传播过程中的一些不足,对一种解析主动蠕虫病毒传播模型进行了改进,提出了蠕虫病毒的两阶段传播模型。仿真结果与CAIDA实际测量的RedCodev2传播数据相比较表明,改进后的模型能更好地描述病毒的传播规律。
In this paper, some existing models about the propagation of worms are briefly introduced, and then a concrete analysis about the effect of Network Address Translator（NAT） on worm propagation is given. To overcome the weakness of traditional models in describing the propagation of worms, a two-phase worm propagation model based on analytical active worm propagation model is proposed. Comparison between the predicted result made by this model and the real propagation data of Red Code v2 measured by CAIDA in 2001 shows that the improved model gives a better description of worm＇s propagation.
