  1. Introduction to the LIN Trial & its transition to a JANET Roaming Service Mark Tysom Authentication & Authorisation Project Manager

  2. Covering… • Background to the Trial • Technology Overview • Current Status of the Trial • Future JANET Service • Parallel International Effort • RADIUS Developments

  3. Terminology • Location Independent Networking (LIN) • eduroam • JANET Roaming Service (JRS) • Three names, one infrastructure!

  4. Background • JANET Wireless Advisory Group (WAG) established May 2003 • Develop a Location Independent Networking infrastructure to enable wired & wireless networks to support guest users in a transparent & secure manner (“visiting scholar problem”) • PoC tests carried out based on RADIUS (Remote Authentication Dial-In User Server) hierarchy

  5. How it works • Hierarchy of RADIUS proxy servers: • Organisational RADIUS Proxy Server (ORPS) • National RADIUS Proxy Server (NRPS) • International RADIUS Proxy Server (IRPS)

  6. For example, using 802.1x to authenticate… Client University of Bristol RADIUS server Institution A (ORPS) UKERNA RADIUS server (ORPS) Authenticator (AP or switch) User DB User DB Guest Username markt@ukerna.ac.uk JANET National RADIUS Proxy server (NRPS)

  7. LIN Trial • Commenced January 2005 • Currently 36 JANET connected organisations • Accepting additional sites on a case by case basis • Ending in January 2006 • Then…?

  8. JANET Roaming Service (JRS)

  9. Sales pitch… • Free service • Launching in Spring 2006 • Resilient NRPS infrastructure • Dedicated support teams • Documentation: deployment, support and user guides

  10. LIN/JRS is part of the eduroam federation • 24 participating European countries plus Australia & Taiwan • IRPS hosted in Denmark and the Netherlands on behalf of TERENA enable international roaming • http://www.eduroam.org/

  11. FWNA (Federated Wireless NetAuth) • Internet2 working group • Trial in early stages • Close collaboration between TERENA and I2 • http://security.internet2.edu/fwna/

  12. RADIUS Developments • Utilising the RADIUS hierarchy infrastructure currently used for authentication • Incorporating authorisation mechanisms, i.e. access to applications • eg. the LICHEN Project
