  4. Abstract:
  5. With the advent of semantic technology, access control cannot be done in a safe way unless the access decision takes into account the semantic relationships between entities in a semantic-aware environment. SBAC model considers this issue in the decision making process. However, time plays a crucial role in new computing environments which is not supported in this model. In this paper we introduce temporal semantic based access control model (TSBAC), as an extension of SBAC model, which enhances the specification of user-defined authorization rules by constraining time interval and temporal expression over users' history of accesses. A formal semantics for temporal authorizations is provided and conflicting situations (due to the semantic relations of the SBAC model and a sub-interval relation between authorizations) are investigated and resolved in our proposed model. © 2008 Springer-Verlag
