Community Hub Unplugged Trust & Identity in Action

Description

This Community Hub event consists of interactively playing RADIUS clients, servers and requests, to understand how authentication works in the eduroam federation. Through a hands-on role-playing activity, we will simulate how eduroam components interact. Some people will take the roles of RADIUS servers and clients, and others will play requests, hopping from proxy to proxy until they reach their home organisation. After the role-playing game, there will also be some time for exchange about current topics in eduroam, such as migration to geteduroam, OpenRoaming and eduroam Visitor Access.
By coming to this meeting, you will learn how an access point can verify that you are actually who you claim to be, even if you come from the other side of the world. You will also discover how RADIUS in eduroam ensures both security and scalability. This is your chance to play with and learn a textbook protocol without reading a book. It is also a nice opportunity to talk to and exchange with eduroam experts in the room.

What will the TNC audience take away from your talk?

Whether you're new to authentication or an expert in the field, you will for sure leave this workshop with a new perception of the infrastructure that keeps you connected every day, ideas on how to explain it in an interactive way and inspirations for future developments.
