【摘要】 近几年,蠕虫频繁爆发,而且传播愈来愈快,破坏力也增大,已成为互联网安全的主要威胁。基于经典的Ker-mack-Mckendrick模型,本文提出了一个采用动态隔离策略、动态传染率和恢复率的蠕虫传播模型。分析表明此模型能更有效降低蠕虫的传播速度,为防御蠕虫赢得更多宝贵的时间,减缓和降低了蠕虫造成的负面影响,仿真试验证明了此模型的有效性。更多还原

【Abstract】 In recent years,the worms that had a dramatic increase in. the frequency and virulence of such outbreaks have become one of the major threats to the security of the Internet. In this paper,we provide a worm propagating model. It bases on the classical epidemic Kermack-Kermack model,adopts dynamic quarantine strategy, dynamic in- fecting rate and removing rate. The analysis shows that model can efficiently reduce a worm’s propagation speed, which can give us more precious time to defend it,and reduce the negative influence of worms. The simulation results verify the effectiveness of the model.更多还原
