Abstract : We introduce an hybrid access control model where abstract pairs consisting of objects and access rights are considered. In this model, an access control matrix is a binary relation of permission between subjects and abstract pairs. Treating sets of subjects as instances of a concept called role and sets of abstract pairs as instances of a concept called entitlement, we introduce in each matrix the binary relations of existential permission and universal permission between roles and entitlements, we analyse their properties, we present the duality between subjects and abstract pairs on one hand and roles and entitlements on the other hand, we extend this duality to the setting with obligations and we demonstrate how this duality is useful by proving the completeness of a propositional modal logic for permissions and obligations.
