【摘要】：針對(duì)惡意軟件在信息物理融合系統(tǒng)中傳播機(jī)理難以描述的問題,利用非線性動(dòng)力學(xué)理論構(gòu)建其傳播動(dòng)力學(xué)模型,并基于穩(wěn)定性理論和Hopf分岔定理對(duì)該模型的復(fù)雜動(dòng)力學(xué)行為進(jìn)行分析.為了控制惡意軟件傳播所引發(fā)的Hopf分岔,根據(jù)分岔控制理論設(shè)計(jì)了一類結(jié)合參數(shù)調(diào)節(jié)法與狀態(tài)反饋法的混合分岔控制策略,并深入研究控制參數(shù)對(duì)Hopf分岔點(diǎn)位置及極限環(huán)幅值的影響.數(shù)值仿真結(jié)果表明所設(shè)計(jì)的混合分岔控制策略不僅能夠提前或推遲Hopf分岔點(diǎn),而且可以改變極限環(huán)幅值大小,使信息物理融合系統(tǒng)產(chǎn)生預(yù)期的動(dòng)力學(xué)行為,實(shí)現(xiàn)控制目的,從而有效降低惡意軟件的危害.
[Abstract]:Aiming at the problem that the propagation mechanism of malware in information physics fusion system is difficult to describe, the nonlinear dynamics theory is used to construct the propagation dynamics model of malware. The complex dynamic behavior of the model is analyzed based on the stability theory and Hopf bifurcation theorem. In order to control the Hopf bifurcation caused by malware propagation, a hybrid bifurcation control strategy combining parameter regulation and state feedback is designed according to bifurcation control theory. The influence of control parameters on the position of Hopf bifurcation point and the amplitude of limit cycle is studied. Numerical simulation results show that the proposed hybrid bifurcation control strategy can not only advance or delay the Hopf bifurcation point, but also change the amplitude of the limit cycle, so that the information physical fusion system can produce the expected dynamic behavior and achieve the control purpose. In order to effectively reduce the harm of malicious software.
