Virtualization of the Circle of Trust amongst Identity Federations
نویسنده
چکیده
This paper explores the concepts that enable a more dynamic setup and building of a Circle of Trust (CoT) amongst multiple and overlapped federations. It examines virtualization-building and driving trends, discusses some models of deployment of the CoT and shines a light on the work of the Liberty Alliance Project as a basis for an extended solution for enlarging dynamically the CoT with new entities. Other challenges of this research rely on the administration of the CoT as well as the life cycle of the participants, which imposes an inherent limit on how new Identity and Service Providers can be added to the CoT and how trust relationships can be established between them.
