为了抑制P2P被动型蠕虫在大规模P2P文件共享网中的传播和攻击,对P2P网络中文件共享的特点和被动型蠕虫传播的特点进行了深入的分析,并在此基础上提出了3个分别适用于蠕虫传播不同阶段的传播模型。为了证明模型的正确性,进行了大规模仿真实验。使用专门的数值分析工具求出相应模型的理论值。为了仿真大规模P2P文件共享网,专门基于P2P仿真平台开发出能真实模拟流行P2P文件共享网的软件并基于该软件进行了仿真。理论值与仿真值匹配的事实表明,该模型基本上反映了蠕虫的传播情况,可以用来预测蠕虫的传播趋势和行为。
In order to restrain the spread and attack of P2P passive worms in large-scale P2P file sharing network, the characteristics of file sharing in P2P networks and the characteristics of passive worm propagation are analyzed in depth. Based on this, Propagation model suitable for different stages of worm propagation. In order to prove the correctness of the model, a large-scale simulation experiment was carried out. Use a special numerical analysis tool to find the theoretical value of the corresponding model. In order to simulate a large-scale P2P file sharing network, a software that simulates popular P2P file sharing network is developed based on P2P simulation platform and simulated based on the software. The fact that the theoretical value is matched with the simulation value shows that the model basically reflects the propagation of the worm and can be used to predict the propagation trend and behavior of the worm.
