摘要
本文基于杀毒软件建立了一个非线性的数学模型,用来研究清理计算机网络病毒的过程。该数学模型把种群中的节点平分为易受感染的、受感染的和受保护的三类群体。借助微分方程稳定性理论,通过数值模拟分析建立的模型,得到了在特定条件下,清理计算机网络病毒取决于网络中受感染节点的如流率、受感染节点和易感染节点的交互速度及他们与杀毒软件的相互作用等;只要杀毒软件能够有效的工作,就能成功的阻止、隔离病毒,保护计算机网络的安全。
This article establish a nonlinear mathematical model based on the antivirus software. Using it, the process of cleaning up computer network virus was studied. In the mathematical model, the total numbers of nodes in the network are divided in three subclasses, namely, the number of susceptible nodes, number of infected nodes and the number of protected nodes. Using differential equation stability theory, obtained that cleaning up the computer network virus depends on the infected nodes flow rate in the network, infection of the infected nodes and node interaction velocity and their interaction with anti-virus software, etc under certain conditions by the numerical simulation analysis to establish the model. At last, we get that as long as the antivirus software can work effectively, it can successfully prevent, isolated viruses, to protect the safety of computer network.
