39 Research of the P2P Worm Defense Mechanism Based on Trust Mechanism Available to Purchase

P2P worm can destroy the entire P2P network in a short time, which turns out to be the biggest security threat of P2P application. In this paper, node trust mechanism is proposed that in-depth exchange of information becomes possible only when the rust between P2P nodes reaches the required threshold so that the P2P worms fast spread can be effectively curbed and the anti-virus system can have sufficient time to find and remove worm viruses. The simulation results show that this mechanism can effectively protect the network against P2P worms attack.
