Abstract: This paper proposes a new model of user behavior decision-making based on the integration of risk and security. The service provider and the user are regarded as the two players in the non-cooperation games, and their interactions are analyzed based on static games model with incomplete information. The game model is built in the point of view that the players choose their actions depending on each other’s action. The mixed strategy equilibriums are derived from the model, and under the mixed strategy equilibriums, the service provider makes the decision such as refusing access or accepting access which can maximize his utility.

Key words: game theory, service provider, user, Nash equilibrium, decision-making
