Quantitative Analysis and Countermeasures Research of P2P Routing Attacks

There are more and more attacks aiming at P2P network, and those attacks take on sophisticated technology and hidden ways, which bring in serious threat to P2P network. Current countermeasure only copes with one certain kind of P2P attack, and is powerless to other attacks or new emerged attack. We have researched features and effects of main P2P attacks with quantitative analysis method, and have found some common characteristics of those attacks. We create a set of mathematical model to descript those attack behaviors, and induce that the rate of malicious nodes in P2P network is the main factor that threat the P2P routing security, and the working efficiency of P2P network and the average length of routing path are other two important threaten factors.
