复杂网络理论是分析许多实际系统的有效途径之一。该文为P2P网络提出了一种基于复杂网络理论的抗攻击模型，其工作机制是基于P2P网络中的动态补偿和反渗滤。该模型能使被攻击的P2P网络转变成具有指数截断的PL网络，能将受攻击的P2P网络中的节点最大度分布恢复到正常水平，且可将被攻击的P2P网络中的破碎节点重新组成一个大的整体。
Complex network theory is a useful way to study many real systems. An anti-attack model based on complex network theory is proposed in P2P networks. The mechanism of this model is based on a dynamic compensation process and a reverse percolation process in P2P networks. The proposed model can turn an attacked P2P network into a PL network with exponential cutoff, can restore the maximum degree of peers in an attacked P2P network to a normal level， and can connects the fragmentary peers of an attacked P2P network together into a giant connected component.
