摘要：
In this paper, we identified the features of passive worm. Further the models of propagation and immunization of passive worms are proposed in the mean-field methods. Based on the model of worm propagation and Epidemiology, the sufficient condition for the global stability of the worm free equilibrium is deduced. Simulations validate the condition. Both the sufficient condition and all the experiment results show that amongst all P2P-related factors having effect on passive wormpropagation, attack performance of passive worms is most sensitive to two P2P system parameters: the download rate and the recovery rate. Controlling the two parameters, i. e. decreasing the download rate and increasing the recovery rate, provides an effective means for throttling the spread of passive worms.
