基于良性蠕虫对抗P2P蠕虫的策略研究

随着P2P软件的推广与普及, P2P蠕虫已成为P2P网络安全的主要威胁之一，P2P蠕虫基于hit-list攻击邻居节点，具有隐蔽性好、攻击性强等特点。基于混合型良性蠕虫概念设计出自动优先趋进优质节点(APTHQN)的对抗策略，合理利用优质节点的拓扑优势，有效适应了P2P网络的动态性。实验仿真结果表明，采用此策略的良性蠕虫在保持较少的网络资源消耗同时，高效地抑制了P2P蠕虫的传播。

Research of policy defending against P2P worm based on benign worm

Through P2P software's popularization P2P worm has been one of the greatest threats to P2P network security. P2P worm attacking neighbor nodes based on hit-list has some characteristics such as good concealment and high infection. This paper presented a new defense policy based on hybrid benign worm named automatic prior tend to high quality nodes(APTHQN). The APTHQN policy not only made use of the topology advantage of high quality nodes but also effectively adapted dynamic of P2P network. The simulation results show that benign worm using APTHQN policy can effectively defend propagation of P2P worm while consuming less network resources.
