A Federated Authorization and Authentication Infrastructure for Unified Single Sign On

Currently federated authorization and authentication infrastructures are deployed to offer services to large groups of users while increasing the usability and scalability of the security architecture. Connection of domains using a variety of technologies brings new challenges and requires the utilization of standardized communication languages between these components. The presented architecture aims to unify types of federations previously separate by using these languages with generic security architecture, able to provide a unified Single Sign On.
