An effects analysis method for C4ISR system structure based on information flow

Aiming at the impact of cyber attack threat on the performance of C4ISR system, a structural effect modeling and simulation method of C4ISR system based on information flow model is proposed. Firstly, the connotation of C4ISR system structure effect is expounded, and two kinds of attack modes and three kinds of attack strategies are put forward. The structure information flow model is established. Based on this, the mathematical model of the damage degree for system structure based on the information flow and mathematical model of fallback effect for system structure based on the information flow delay are proposed. Finally, the method of C4ISR system structure effect simulation is validated by taking the simulation experiment of a regional command and control system as an example.
