Research of P2P Routing Security Based on Positive Detection Mechanism

Routing is a critical factor to ensure the stabilization and normal communication of P2P network. If routing is interrupted, the communication efficiency will deteriorate and even cause the crash of the whole P2P system. The widespread problem of existing P2P routing mechanisms is their poor anti-attack. The paper proposes a safe routing algorithm based on positive detection mechanism, which can detect abnormal peers in the routing path and exclude them. In addition, the algorithm can decrease length of routing path, reduce communication delay, but without loss anti-attack capability. The simulated experiment demonstrates that the new algorithm has obvious effect on raising anti-attack capability of P2P network, and improves safety and efficiency.
