RelBAC: Relation Based Access Control

Goal The key idea, which differentiates RelBAC from the state of the art, e.g., Role Based Access Control (RBAC), is that permissions are modeled as relations between users and data, while access control rules are their instantiations on specific sets of users and objects. As consequence RelBAC can easily model problem difficult to express using RBAC.
