中文摘要： 访问控制中应用系统与其用户之间存在各自利益最大化的博弈。博弈论能为复杂的访问控制决策提供有效的数学理论和方法。合理的成本效益访问控制决策博弈模型是个重要的研究课题。本项目着重研究博弈论在访问控制领域内的应用。首先考虑到访问控制中用户信任和资源访问风险的客观存在性，将信任和风险相结合。其次通过构建访问控制决策博弈模型，求出基于信任和风险的最优策略，从而提高访问控制的灵活性。访问控制限制问题也通过阶段性博弈的最优策略得以解决。最后研制该博弈模型的访问控制测试系统。

英文摘要： In access control, there exists a game between application system and its user in which both of them try to maximize their own utility. A reasonable access control game model of cost-benefit analysis is a important research issue. In this project, we mainly research on the application of game theory in the area of access control. Firstly, considering the real existence of user trust and risk of resource access, we will correlate the trust and risk. Secondly, via constructing access control decision-making game model, find the optimal strategy based on trust and risk,so that improve the flexibility of access control.Thirdly, we also solve the problem of access control constraints using multi-stage game optimal strategy, Finally, we will design and implement prototype access control testing system based on the above game model.
