Özet:   Delegation of authority allows users and services to delegate other users and services authority to access resources. Delegation is an important aspect in access control models. Role-based access control (RBAC) is being recognized as an efficient access control mechanism that facilitates security administration but RBAC is not expressive enough to deal with all delegation requirements. The existing delegation models assume that a user must be available to make the delegation and must know the delegate. To achieve a higher level of flexibility and dynamic resource management, it is worthwhile supporting Auto-Delegation mechanism for RBAC. In proposed model, we develop an access control model based on RBAC to support Auto-Delegation decisions. Output of this research is an execution model and evaluated in an implementation case study.
