摘　　要：由于不同的漏洞编制出不同的沉默型P2P蠕虫对于网络可能造成巨大危害性.提出多种沉默型P2P蠕虫共同传播的数学模型.首先,对多种沉默型P2P蠕虫的传播进行了建模,主要分为共存和不共存两种情况.在共存情况下,推导多种沉默型蠕虫的瀑布型模型;在不共存情况下,分别推导多种沉默型P2P蠕虫的直线型、直角型和渐进型模型.然后,分别讨论了各种情况下蠕虫不会泛滥的条件、无病平衡点、地方病平衡点以及达到平衡点时的稳定性分析.最后,通过仿真实验对于模型进行了验证.Due to different vulnerabilities are able to prepare a different reactive-P2 P worm,this may cause a great harm to the Internet.In this paper,a mathematical model of multi-reactive-P2 P-worms spreading together is proposed. Firstly,we model multi-reactiveP2 P-worms spreading together and classify it into two parts： coexistence and non-coexistence. The waterfall model is derived in the situation of coexistence,and straight model,right angle model,and gradual model in the situation of non-coexistence are derived. Then,we discuss non flooding condition,disease-free equilibrium point,endemic equilibrium point and stability analysis of equilibrium point under various circumstances. Finally,we simulated and validated the model.
