无尺度半分布式P2P僵尸网络的构建

Construction of Scale-free Semi-distributed P2P Botnet

鉴于僵尸网络具有无尺度网络的增长性和择优连接性,提出一种无尺度半分布式P2P僵尸网络的构建方法。僵尸程序在初始时只感染少数几台主机,之后每台受感染主机根据节点度数选择要连接的节点,度数越大,节点被感染的概率越高。理论分析和仿真结果表明,利用该方法构建的僵尸网络具有无尺度网络的2个重要特性。

Botnet has two features of scale-free network,so this paper proposes a construction method of scale-free semi-distributed P2P Botnet.It allows the bot program to infect a few hosts,after that,each infected host choose the node according to its degree.The degree is larger,the probability of selection is higher.Theoretical analysis and simulation results show that the Botnet constructed by the method has the features of scale-free network.
