[0022] (1)

[0023] in

[0024] (2)

[0025] Among them, the system represent the vulnerable and infected programs of the network computer respectively, this model involves five parameters, represents the capacity of the network, Indicates the recovery rate of infected computers due to the antivirus capabilities of the network, Indicates the rate at which a computer is removed from the network, Indicates the rate at which a computer can become susceptible to a computer infection when connected to another infected computer. represents the initial infection rate. When certain parameters are given, the system has a scroll attractor. when parameter =0.01;k=600;d=0.5; =0.5; m=4.5; I0=9, the chaotic attractor phase diagram of system (1) can be obta...

Abstract

The invention provides a novel computer anti-virus propagation model in view of influence of anti-virus ability on the network. A two-dimensional mapping equation is obtained through analysis of relationships between system parameters. A dynamic behavior of the system is analyzed from the angles of a bifurcation diagram, a Lyapunov index and a parameter space three-dimensional bifurcation. Rich phenomena such as bifurcations and intermittent chaos can happen to the system, and the system has a chaos attractor. Finally, according to a two-dimensional chaotic system based on computer virus resistance, the fact that results such as a state and change of the system in a two-parameter space can facilitate understanding the rule that a computer virus is transmitted through a computer network is disscussed.

Description

technical field [0001] The invention relates to a computer anti-virus two-dimensional chaotic system, which belongs to the field of computer and nonlinear control. Background technique [0002] It is a very common phenomenon that bifurcation and chaotic state appear due to the instability of motion state of nonlinear dynamical system. Chaotic behavior is characterized by sensitivity to initial values, ergodicity, seemingly randomness, and has a very complex fractal and self-similar structure. During the gradual and in-depth study of chaotic behavior, the orderly phenomenon hidden behind the surface chaos of chaotic behavior is revealed, and it is found that chaotic behavior has many benefits for simulating many phenomena in nature. In recent years, the research on the chaos phenomenon in computer anti-virus ability has become one of the hotspots in the field of computer science. Studies have shown that anti-virus capability is a typical nonlinear time-varying system, and u...
