3. The t-Infrastructure Why t-infrastructure?
e-Infrastructure for production
training infrastructure (t-Infrastructure) for training
Need guaranteed response for tutorials; limit the vulnerability of production systems
use training grid
have training CA
able to change middleware to prepare participants for future releases on production system
Also:
need safe resources for installation training
easy entry point for new communities

12. The Genius portal project
At the beginning of 2002 the Italian INFN GRID Project started the GENIUS Portal Project in conjunction with the Italian web technology company NICE srl
The present implementation of the GENIUS grid portal described here is carried out on the top of the gLite middleware services
Location, Meeting, dd.mm.yyyy

13. GENIUS GRID portal features 1/2
It can be accessed from everywhere and by “everything” (desktop, laptop, PDA, cell phone).
The same user interface to several back-ends.
All available grid services incorporated in a logic way, just “one mouse click away”.
Layout easily understandable and user friendly.
Location, Meeting, dd.mm.yyyy

14. GENIUS GRID portal features 2/2
Secure at all levels:
1) secure for web transactions
2) secure for user credentials
3) secure for user authentication
4) secure at VO level.

execution
From a ”trusted” machine the user can, using the private key of his X.509 personal certificate, create a temporary certificate issuer (a myproxy) and store it, for a defined amount of time, on a MyProxy Server
When the user asks the GENIUS portal to invoke a Grid service, the portal contacts the MyProxy Server and tries to get a temporary proxy certificate on the user’s behalf . If the life time of the myproxy is not expired, temporary user credentials are retrieved, the action is performed and the output is rendered back into the user’s web browser. So, the three-tier architecture of MyProxy’s credentials delegation avoids the private key of the user’s certificate to be sent over the network, avoiding a security hole.

41. Summary and Conclusions
GILDA is a virtual laboratory for dissemination of grid computing:
It is a “de facto” standard t-Infrastructure adopted both by EGEE and many EU-FP6 projects (EELA, EUCHINAGRID, EUMEDGRID, ICEAGE, etc.)
It is a complete suite of grid elements (test-bed, CA, VO, monitoring system, web portal, user interfaces, support system) and applications fully dedicated to dissemination purposes and pre-porting of new applications to EGEE Infrastructure
GILDA runs latest production version of the gLite middleware to make the transition from the t-Infrastructure to the e-Infrastructure easy and transparent
