Simulation and analysis on propagation of man-activated worms in P2P network

This paper studied the propagation mechanism of the man-activating worm,which was a kind of active worms in the P2P network.The propagation procedure of this kind of worm consists of four stages: information collection,penetration,self propulsion and activating.It was found that the worm was a kind of topology-awareness worms.It could properly identify the patent target by exploiting the neighbor information,which was stored in its cache.This may made it very difficult to detect it.For the purpose of examining the effect of P2P-related parameters on propagation of the worm,developed simulation program.Simulations experiments show that amongst all the P2P-related parameters,the probability of worm being activated rather than the attacking rate has the most effect on worm propagation.
