Abstract :
Currently, delegation models with time constraints are focused on RBAC and DAC models and doesn´t support TRBAC (task_role_based access control) model. This paper presents a delegation model with time constraints for TRBAC model, called TTRBDM. TTRBDM uses time constraints and task revocation to control delegation. Authors give the conceptions of the task delegation and the task revocation, formally describes delegation authorization rule and task revocation steps for TTRBDM and prove the execution model controllability to show that it provides the foundation for applications executing the permission delegation.
