Abstract

We here describe an access control model for securing temporal XML document. Our approach is based on a temporal data model allowing to represent both transactional and valid time dimensions of XML documents. The authorization model allows the specification of temporal conditions on the two considered time dimensions and on the validity of the authorizations.
