Abstract

We extend the XACML reference implementation so that a policyset consisting of remote references to other policies can be evaluated distributively. Our extension also covers requests to resources that need to be used exclusively. We do so by implementing a nested transaction model for the evaluation of distributed XACML policies. Experiments show reasonable performance of our access controller.
