中文摘要：

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,提出一种无尺度网络下具有免疫特征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被移除而具有免疫特征的情况。通过MATLAB进行仿真,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。

英文摘要：

Combining the features of scale-free network and immunity, this paper proposed a new botnet propagation model with immunity on scale-free network. The model considerated carefully about the real situation of the Internet, especially the scale-free network topology and immunity of the host which removed from the susceptible network in advance. Simulation result shows that the botnet propagation model more exactly satisfies the practical propagation laws and infection characteristics of bot on Internet.
