Abstract

This paper mainly aims to explore the propagation behaviors of computer virus over complex networks under the combined effects of network topology and removable storage media. To this end, a dynamical model is established and analyzed theoretically, including the outbreak threshold, equilibria and their global dynamics. It is found from the systematic analysis that the virus will die out or persist in the network depending on the outbreak threshold, which is associated with the network topology and removable storage media. Moreover, a set of well-designed experiments are performed over the Oregon routing network to verify the proposed model and its theoretical analysis results. Experimental results show that the predicted results of the model are in good agreement with the simulation results over the above network, and the removable storage media have a great effect on viral spread. To this regard, some preventive measures against virus infection are recommended.

复杂网络上计算机病毒的传播行为分析：以俄勒冈州路由网络为例

摘要

本文的主要目的是探讨在网络拓扑和可移动存储介质共同作用下，计算机病毒在复杂网络上的传播行为。为此，建立了动力学模型并从理论上进行了分析，包括爆发阈值，平衡及其全局动力学。通过系统分析发现，病毒将根据爆发阈值而消亡或保留在网络中，爆发阈值与网络拓扑和可移动存储介质相关。此外，在俄勒冈州的路由网络上进行了一组精心设计的实验，以验证所提出的模型及其理论分析结果。实验结果表明，该模型的预测结果与上述网络的仿真结果吻合良好，可移动存储介质对病毒传播有很大影响。为此，建议采取一些预防病毒感染的预防措施。
