Abstract:

In order to improve the signal recognition ability and defense effect of network platform in attack defense confrontation, the signal game model and migration strategy of multi-stage platform dynamic defense are proposed. Firstly, starting from the principle of platform dynamic defense, this paper analyzes the topology structure and game flow of platform dynamic defense, constructs the signal game model of multi-stage platform dynamic defense, gives the definition of attack and defense revenue parameters, introduces detection and detection factors, and analyzes the impact of information obtained by both sides on the next stage of the game. Secondly, according to the signal game process, the refined Bayesian equilibrium solution method of multi-stage equilibrium strategy is demonstrated, and then the optimal migration strategy selection algorithm of multi-stage platform dynamic defense is proposed. Finally, the effectiveness of the proposed model and strategy is verified by examples and simulations.

Key words: platform dynamic defense, signal game, multi-stage, migration strategy
