本文提出了一种新的计算机病毒传播模型,该模型考虑了在抗病毒能力有限的网络上病毒爆发的可能性。然后,研究了该模型平衡点的存在性,并证明和说明了平衡点的稳定性。此外,发现这两个因素不仅与决定病毒是否灭绝的阈值有关,而且与病毒流行水平有关。理论和实验结果表明,在某些方面,根除该病毒或将其流行抑制在适当水平以下实际上是可能的。因此,提出了一些建议,可能有助于消除或抑制病毒传播的真实的计算机网络。
This paper describes a new computer virus spreading model which takes into account the possibility of a virus outbreak on a network with limited anti-virus ability. Then, the model is investigated for the existence of equilibria and their stabilities are proved and illustrated. Moreover, it is found that these two factors are not only relative to the threshold value determining whether the virus becomes extinct or not, but that they are also relative to the virus epidemic levels. Theoretical and experimental results indicate that, in some ways, it would be practically possible to eradicate the virus or suppress its prevalence below a suitable level. Consequently, some suggestions are proposed that may help eradicate or suppress virus propagation over a real computer network.
