Analysis and control stratagems of flash disk virus dynamic propagation model
Computer virus mainly contain two kinds: network viruses and flash disk (FD) viruses, we name viruses as FD-virus which spread by the latter way. Many researchers have studied the network virus in light with epidemiology such as susceptible-infected-susceptible, susceptible-infected-recovered, susceptible-exposed-infective-recovered (SEIR) and susceptible-infectious-detected-removed, but there are few studies on FD virus propagation. In this paper, a new dynamic propagation model of FD-virus, namely FD-SEIR, is discussed. Unlike other existing computer virus propagation models, FD-SEIR mainly considers the FD-virus propagation between host and FD, which is embodied by introducing the FD state and new propagation rate. Furthermore, several related dynamics properties are investigated, along with the analysis of how to control the FD-virus prevalence based on the equilibrium stability. The simulation results show that the proposed model can serve as a basis for understanding and simulating FD-virus epidemics. Copyright (C) 2011 John Wiley & Sons, Ltd.
