A WAW Model of P2P-based Anti-worm

With more and more worms plunge into the Internet, worm-anti-worm (WAW) becomes a new active countermeasure. In this paper, a new P2P-based anti-worm is proposed. To illustrate the propagation of worms and anti-worms, TF-SEI (two-factor-SEI) model is given. By comparing our model with the traditional anti-worm model, we observe that the worm-infected hosts can approach to zero with shorter time in our model. We also find that P2P-based anti- worm performs better in controlling worm propagation, even if the delay time is longer.
