摘要: 蠕虫利用多种技术来实现快速传播。近年来得到广泛应用的组播技术可能被蠕虫用来加速蠕虫传播过程。本文通过分析组播蠕虫的传播模式,建立了组播蠕虫传播模型并用数值分析方法对影响蠕虫攻击性能的因素进行了研究。根据数值结果得出组播蠕虫的攻击性能与几个因素密切相关。

Abstract: Worm can use many kinds of technologies to fast its propagation. Widely used multicast technology in recent years would be used to fast worm propagation. This paper builds multicast-worm propagation model by analyzing propagation mode of multicast-worm and uses numeric analysis approach to research the impact of several factors relative to worm attack performance. From numeric results, we observe that multicast-worm attack performance is very sensitive to these factors.

Key words: Worm propagation, Multicast, Epidemic model
