1. Solving the Middleware Puzzle Ton Verschuren - SURFnet JISC – SURF – Internet2 workshop Oxford, September 19-20, 2002

2. 2 The Middleware Puzzle Authentication Systems ? Back Office Authorisation Systems Applications

3. 3 Our efforts in solving the puzzle Authentication: –Student Smartcard (1996-2000) –PKI (???-???) –Internet banking (2001-…) –Mobile phone & SMS (2001-…) –Username/password + RADIUS (1999-…) Authorisation: –First look at PAPI –In near future Shibboleth –Nordic efforts

4. 4 Standards The good thing about standards is that there are so many to choose from Any well-defined API will do for now SAML? Surfing the waves of the Web Services hype? IMS for ELEs, but how to integrate with other schemas? GRID standards?

5. 5 Collaboration areas Fitting together the European pieces of the puzzle (PAPI, A-Select, Policy Server, Athens- ng, GRID middleware) Validating the Internet2 output for Europe (Shib, EduPerson, …) Establishing a European counterpart of I2 MACE: TERENAs TF-AACE? Using middleware systems for delivering services –E.g. guest access to institutional WLANs –EduServ services?
