Abstract: Most work on XML access control considers XML nodes as the smallest protection unit. This paper shows the limitation of this approach and introduces an XML access control mechanism that protects inter-node relationships. Our approach provides a finer granularity of access control than the node-based approaches(i.e., more expressive). Moreover, our approach helps achieve the “need-to-know” security principle and the “choice” privacy principle. This paper also shows how our approach can be implemented using a generic label infrastructure and suggests algorithms to create/check a secure set of labeled relationships in an XML document.
