Harvesting the benefits of different identity federation architectures

The architectural differences between peer-­‐to-­‐peer identity federations and hub-­‐and-­‐spoke identity federations are profound but both have their advantages. In order to get the organisational and scalability features of the hub-­‐and-­‐spoke architecture as well as the usability advantages of the peer-­‐to-­‐peer architecture a transparent proxy infrastructure has been implemented by WAYF – Where Are You From, a national Danish identity federation.
