具有切换特性和免疫控制的计算机病毒传播模型
A COMPUTER VIRUS PROPAGATION MODEL WITH SWITCHING CHARACTERISTICS AND IMMUNE CONTROL
摘要
Abstract
Aiming at the current computer virus propagation modeling research that does not comprehensively consider the impact of security protection and continuous virus updates,this paper proposes a computer virus SEIR(susceptible-exposed-infected-recovery)propagation model with switching characteristics and immune control.Considering the impact of security protection measures and virus updates,a switching virus propagation model was constructed,which was composed of a low protection subsystem and a high protection subsystem.Considering the immune control strategy,a switching pulse virus propagation model was constructed.In order to verify the effectiveness of the model,numerical simulations were performed on the BA scale-free network and the SW small-world network,and a comparative analysis was carried out.The experimental results show that the immune control strategy in the SW small world network can effectively control the spread of the virus;the ratio of the low-protection transmission period to the high-protection transmission period is smaller,the density of latent nodes and infected nodes is smaller when it reaches a plateau.The longer the update cycle,the lower the peak density of latent nodes and infected nodes.关键词
