无尺度网络下的僵尸网络传播模型研究
New propagation model of Botnet on scale-free network
摘要
Abstract
Botnet is a novel attack strategy evolved from the traditional malicious softwares. It has become a major threat to Inter-net security. Propagation model of Botnet has become one of the most efficient methods to research the propagation inherent char-acteristics of bots. Currently the mainstream propagation model of Botnet is almost based on random network, and the actual Inter-net is a complex network with scale-free feature, so these mainstream propagation models can not exactly describe how the bots spread on Internet. In this paper, a new propagation model of Botnet on scale-free network is proposed, which considers carefully about the real situation of Internet with network traffic congestion what is a normal phenomenon on Internet, especially two key factors including growth and preferential attachment. The simulation result indicates that this propagation model of Botnet more exactly confirms with the propagation principle and the inflection feature of bots on actual Internet, and it reflects the infection characteristics of bots when the network congestion occurs.关键词
