In order to promote mutual trust and win-win cooperation between the users and the providers, we propose a trust-game-based access control model for cloud service in the paper. First, we construct a trust evaluation model based on multiple factors, such as the direct trust, feedback trust, reward punishment, and trust risk and further propose a weight method by maximum discrete degree and information entropy theory; second, we combine trust evaluation with the payoff matrix for game analysis and calculate the mixed Nash equilibrium strategy for the users and service providers; third, we give the game control condition based on trust level prediction and payment matrix to encourage participants to make honest strategy. Experimental results show that our research has good effect in terms of acceptance probability, deception probability, accuracy of trust evaluation, and cooperation rate in the cloud service.

基于信任游戏的云服务访问控制模型

为了促进用户与提供商之间的互信与共赢，本文提出了一种基于信任游戏的云服务访问控制模型。首先，基于直接信任，反馈信任，奖惩，信任风险等多种因素构建信任评估模型，并基于最大离散度和信息熵理论提出权重法。其次，我们将信任评估与收益矩阵相结合进行博弈分析，并为用户和服务提供商计算混合纳什均衡策略。第三，基于信任度预测和支付矩阵给出游戏控制条件，鼓励参与者制定诚实的策略。实验结果表明，我们的研究在接受概率，欺骗概率，
