Abstract:
Authorisation solutions that exist today offer a broad range of functionality for defining complex access control policies. A common requirement that is not covered by these solutions is dynamically instantiated contexts in collaborative environments. This requirement is one of the research topics of the EU funded INTEGRATE project. This paper will focus on the solution proposed for the INTEGRATE project which is XACML based. The approach taken to make XACML context aware, is to enrich the XACML specification using a contextual extension through a generic mechanism, without changing the XACML language itself. This contextual extension operates on the XACML requests with ultimate goal to simplify the management of context aware policies.
