Abstract: In order to get closer to the reality of the network, aiming at the imbalance of information of network attack-defense and the dynamics of network confrontation, a signaling game model with active defense is proposed. In the condition of incomplete information, the game tree of attack-defense strategy is built to model the strategies of attackers and defenders, and the success rate of the attack strategy is reduced by using the camouflage signal. Based on the analysis of the equilibrium, the game model is designed and the optimal defense strategy is given. Finally, through the analysis and summary of the experimental results, the maneuverability and effectiveness of the model are proved.
