We study the complexity of satisfiability for DLP+ dyn , an expressive logic introduced by Demri that allows to reason about dynamic policies. DLP+ dyn extends the logic DLPdyn of...
Access-control policies have grown from simple matrices to non-trivial specifications written in sophisticated languages. The increasing complexity of these policies demands corres...

People often need to reason about policy changes before they are adopted. For example, suppose a website manager knows that users want to enter her site without going through the w...
We argue that joint administration of access policies for a dynamic coalition formed by autonomous domains requires that these domains set up a coalition authority that distribute...
Abstract. We present a modelling language, called X-Policy, for webbased collaborative systems with dynamic access control policies. The access to resources in these systems depend...
