摘　　要：对P2P触发式主动型蠕虫的攻击机制进行了研究,发现该类蠕虫传播通常包括四个阶段:信息收集,攻击渗透、自我推进与干预激活.基于对P2P触发式主动型蠕虫攻击机制的分析并运用流行病学理论提出了P2P触发式主动型蠕虫传播数学模型并基于该模型推导了蠕虫传播进入无蠕虫平衡状态的充分条件.仿真实验验证了所提出传播模型的有效性.As a kind of proactive worms in the P2P network,the artificial-activation worm is studied in terms of attac-king mechanism in this paper.The propagation procedure of this kind of worm consists of four stages：information collection, penetration,self propulsion and artificial activation.It is found that the worm is a kind of topology-awareness worms.Based on the analysis on the attacking mechanism of this kind of worms,the mathematical model of artificial-activation P2P proactive worm propagation is proposed.Further,the sufficient condition of worm propagation attaining the worm free equilibrium is de-duced from the model in applying Epidemiology.Large scale simulation experiments validate this proposed model.
