An Authorization Mechanism for Resource Space Model

摘要：

Authorization mechanism is an effective technique of access control. In this paper, we construct a multidimensional authorization space for RSM with the guidance of the methodology of RSM design. This authorization space permits both positive and negative authorizations and supports exceptions and strong enforcement as well as the temporal constraints on the authorizations. For the sake of efficiency and convenience we extend the representation of object in GRANT command.
