We describe an approach for distributed access control policies that is based on a nonmonotonic semantics and the use of logic programming for policy specification and the evaluation of access requests. Our approach allows assertions of relevance to access control to be made by individual agents or on a community-based level and different strengths of testimonial warrant may be distinguished by using various logical operators. We describe a form of ASP that allows for remote access request evaluation and we discuss a DLV-based implementation of our approach.
