Optimal Network Defense Decision-making Method Based on Delay-Time Differential Game

In the process of attack and defense, there will be a period of delay in the implementation of the decision-making and strategy, therefore, the paper is based on the theory of the dynamic and time-delay differential game theory, and puts forward the network security status evolution model, and puts forward the network attack defense delay differential game model, and the design of the method of the optimal defense strategy of the most optimal defense strategy is designed, and the optimal decision is achieved. Finally, the validity of the model and the algorithm is verified by experiment.
