主 题:Fine-grained access control Database security Prohibition Multiple policies
摘 要:Fine-grained access control (FGAC) must be supported by relational databases to satisfy the requirements of privacy preserving and Internet-based *** much work on FGAC models has been conducted,there are still a number of ongoing *** propose a new FGAC model which supports the specification of open access control policies as well as closed access control policies in relational *** negative authorization is supported,which allows the security administrator to specify what data should not be accessed by certain ***,multiple policies defined to regulate user access together are also *** definition and combination algorithm of multiple policies are thus ***,we implement the proposed FGAC model as a component of the database management system (DBMS) and evaluate its *** performance results show that the proposed model is feasible.
