description In current paper, a delayed SEI2RS malware dissemination model in cyber–physical systems is proposed. Effect of the time delay owning to temporary immunity interval of the recovered nodes is analyzed. A series of sufficient criteria determining local stability of malware-existence equilibrium and occurrence of Hopf bifurcation are revealed via regarding the time delay owning to temporary immunity interval of the recovered nodes as bifurcation parameter. Additionally, direction and stability of the Hopf bifurcation are explored with the aid of the center manifold theorem and normal form theory method. At last, numerical calculations are conducted to prove validity of obtained results.
