Modeling Propagation of Active P2P Worm in Chord Network

P2P worms utilize the topology of P2P network, gaining a better propagation effect compared with random scanning worm. The active P2P worm is the most destructive P2P worm, which would generate infection target list from P2P nodes' neighbor information to achieve faster propagation speed and more concealment. Worm propagation in Chord network is special due to the fact that Chord network is structured P2P network. We proposed a propagation model for active P2P worm in Chord network, which fits the structure of Chord. We carry out simulation studies, which indicate that our model is able to describe the propagation of active P2P worm in Chord network well. Further simulation shows that worm takes extremely short time to infect the whole Chord network, suggesting that Chord network is a nice environment for worm propagation.
