Research of Key Nodes of Botnet Based on P2P

摘要: The paper applies the segmentation of peer-to- peer network to defense process P2P-based botnet, in order cause greatest damage on P2P network. A lot papers have been researching how find key nodes networks. To solve this problem, proposes distributed detection algorithm NEI and centralized COR for detecting cut vertex, not only apply detect vertex directed graph but also undirected graph. can reduce additional communication. Then, carries out simulation results show that maximum botnet be achieved by destructing nodes.
