Abstract—In order to solve the shortage of the access control method based on role and credit, a novel dynamic credit and role based access control method is proposed. The method controls an entity’s access behavior through its credit value, and introduces penalty and feedback mechanism to dynamically adjust entity’s credit value. In order to manage an amount of entities effectively, entities with different credit values are divided into different roles in system, and roles are assigned to corresponding privileges respectively. Experimental simulation results showed that the proposed method has good controllability of entity’s credit value and manipulability to protect system’s resources.
