| Abstract: | The creation of dynamic coalitions is a challenging task, seen from a security perspective. Due to the
presence of con?icting requirements and speci?cations, the policy negotiation and policy merging processes
call for the use of e?cient techniques to resolve ambiguities. Constraints and constraint programming
on the other hand, are useful means for representing a wide range of access control states and access
control problems. In this paper we utilize constraints to represent access control policies in a multi-domain
environment. In contrast to monolithic (crisp) constraint satisfaction techniques, we extend the applicability
of constraints for access control, by examining soft constraints and partial constraint satisfaction. We also
introduce a security framework based on fuzzy constraints that allows the determination of preferences for
the participating domains. |
