Access control is the basic of information security. It is always used to protect sensitive information and critical resources from malicious attacks. But the traditional access control models are more adapt to closed network environment. And there are more and more unknown threats and attacks in the open networks, especially the mobile networks. To solve this problem, we propose a new access control model which is applicable to the open mobile networks by using non-zero-sum game theory in this paper. The model is composed by six modules: access evaluation module, access permission determination module, non-zero-sum game theory analysis module, decision-making module, result evaluation module, access feedback module and a prior information database. And in this model, the subjects will choose to be more honest when they make access requests because they all want to get more permission next time. Then we do some experiments to prove this fact.
