The T-RBAC model has a wide range of applications in various fields, but has certain disadvantages. Aiming at the shortcomings of T-RBAC model in task assignment and authority management, an improved model is proposed. The new model simplifies the task classification of T-RBAC model. Considering the task context, task time limit, and task status attributes, the role manager, task manager, and authority manager are introduced, and the grant of authority is closely linked with the three managers, which enhances the dynamic management of rights. The constraints are strengthened and expanded to ensure dynamic separation of duties during task execution. The model has finer-grained rights management, better meets the principle of separation of duties and least privilege, and has higher security.
