摘要：Conventional access control models are suitable for centralized and static environment, but they seldom meet the requirements of open and dynamic environments. The design of effective access control models to meet the challenge is a current research focus. As an important factor in security, trust is increasingly applied to security management, especially in access control. In this paper, by considering multi-factors feature of trust, we proposed an access control model based on multi-factors trust. The model includes multi-factors trust computation, permission mapping and feedback module. Simulation results show that the model is suitable for access control in dynamic environments.
