Propagation modeling and analysis of viruses in P2P networks

To counter the attacks of virus in P2P file-sharing networks, the model of virus propagation in P2P networks is proposed based on deep analysis on the features of file sharing and virus propagation. In order to examine the effects of different parameters in this model, large scale simulating experiments are carried out. The numerical analysis on the impact of P2P-relatedfactors such as number of initially infected peers, downloading rate, recovery rate, etc, shows that attack performance of viruses is very sensitive to P2P system parameters.
