Formal Authorization Allocation Approaches for Role-Based Access Control Based on Relational Algebra Operations


In this paper, we develop formal authorization allocation algorithms for role-based access control (RBAC). The formal approaches are based on relational structure, and relational algebra and operations. The process of user-role assignments is an important issue in RBAC because it may modify the authorization level or imply high-level confidential… (More)
