Framework for Agent-Based Role Delegation

This paper describes a framework for addressing the administration of role delegation introduced in the well-known role-based access control model (RBAC). More specifically, this paper describes how a third party, called an agent, can administer the delegation of roles on behalf of a user who is a member of a certain role and wishes to delegate his role to another user who belongs to another role. Furthermore, this paper describes a framework of reference to systematically address the diverse manifestations of the agent-based delegation, such as Role participant agent, non-role participant agent, static, and dynamic types of delegation and introduces an agent-based delegation model that illustrates delegation based on non-role participant delegation.
