无尺度网络下具有双因素的僵尸网络传播模型

随着网络技术的发展,僵尸网络逐渐成为Internet上最具威胁的攻击平台.而现今的网络是随机网络、无尺度网络等构成的一个复杂网络.结合无尺度的特性,考虑僵尸网络传播过程中部分主机的免疫特性与网络阻塞特征,提出一种无尺度网络下具有双因素的僵尸网络传播模型.该模型基于Internet的实际情况,重点考虑了无尺度网络的拓扑结构,并结合了僵尸网络中部分脆弱主机由于提前从易感染的网络中移除而具有的免疫特征情况与传播过程中的网络流量阻塞情况.Matlab仿真结果表明,这种传播模型更符合真实网络中僵尸网络的传播规律.

Botnet Propagation Model with Two-factor on Scale-free Network

With the developing of network, botnet has become a major threat attack platform w Internet, The current network is a complex network consisting of the random network and the scale-free network. This paper, combining the features of scalcfree network, immunity and network traffic congestion, proposed a new botnet propagation model with two-factor on Scal}free network. This model considers carefully the real situation of the Internet, especially the Scale free network topology, immunity of the host removed from the susceptible network in advance and network traffic congestion. Simulation result shows that the botnet propagation model more exactly satisfies the practical propagation laws and infection characteristics of bot on Internet.
