title = "A rule-based framework for role-based delegation",
abstract = "In current role-based systems, security officers handle assignments of users to roles. However, fully depending on this functionality may increase management efforts in a distributed environment because of the continuous involvement from security officers. The emerging technology of role-based delegation provides a means for implementing RBAC in a distributed environment with empowerment of individual users. The basic idea behind a role-based delegation is that users themselves may delegate role authorities to other users to carry out some functions on behalf of the former. This paper presents a role-based delegation model called RDM2000 (role-based delegation model 2000), which is an extension of RBDM0 by supporting hierarchical roles and multi-step delegation. The paper explores different approaches for delegation and revocation. Also, a rule-based language for specifying and enforcing the policies based on RDM2000 is introduced.",
