Research on cost budget model of information security based on Game Theory

Abstract

In the face of the widespread use of information technology today, the information security problem has begun to receive extensive attention. In this paper, based on game theory, the cost budget model of information security was studied and analyzed, and the minimax fuzzy game model was proposed. In this model, evidence theory was used to describe the fuzziness of information, and the minimax regret principle of acceptable income was introduced to avoid unacceptable gains and excessive pessimism. The minimax fuzzy game model was applicable to multiple attackers and multiple defenders, and attackers and defenders need not observe their strategies first, so that they can act at the same time.
