Abstract
A system and method grants security privilege in a communication system by providing privilege test criteria data for a subscriber unit so that the subscriber unit or some other entity can select among subscriber privilege data based on the privilege test criteria data, so that only the necessary privilege information is communicated between the relying party and the subscriber unit of interest. A privilege data selector selects, for example, among a plurality of attribute certificates associated with a selected subscriber unit or among sets of privilege data within an attribute certificate, the certificate (or certificates) that matches the privileged test criteria data. This pre-selected certificate is then communicated for use by the relying unit and verified that it meets the test selected by the relying party unit.
