  1. European Grid Infrastructure AAI in EGIStatus and Evolution Peter Solagna Senior Operations Managerpeter.solagna@egi.eu GergelySipos Technical Outreach Manager gergely.sipos@egi.eu

  2. European Grid Infrastructure • European • Over 35 countries • Grid • Secure federation of IT resources, computing storage and applications • Infrastructure • More than 340 resource centres • HTC and cloud services • For European researchers and their international collaborators • EDGEGEEEGI • Supporting research for over 10 years • More than 200 user communities, 20k users EGI.eu

  3. Authentication and Authorization in EGI - 1 Authentication: • X.509 personal certificates from IGTF Certification Authorities • CA available in every country • Supported by several Registration Authorities distributed • TerenaCertificate Service for eduGAIN users • Catch-all CA provided by EGI.eu Authorization: • Based on attributes provided by the user communities • Virtual Organization membership • Roles and groups within the VO

  4. Authentication and Authorization in EGI - 2 TRUST TRUST Virtual Organization

  5. The key is: collaboration • Authentication and Authorization workflows scale with the number of service providers and users • User identity is verified by the IGTF Certification Authorities who release the X509 certificates • The certificate enable uniform authentication of the user across resource centres • User communities have the tools to manage the membership of their users and their structure • Collaborate to the trust chain and to integrate the information provided by the Identity Providers • Authorization is based on the Virtual Organization membership and attributes not on the single user identity • The user capabilities based on groups and roles within the VO are reflected into uniform access rights across the sites that support the VO

  6. Extend the X509 mechanism • For some users approaching EGI the X509 mechanism is a barrier • They do not have easy access to a Certification Authority • They would prefer to continue using their institutional credentials • VOs and Resource Providers implement portals to ease the access to the resources • The most effective solution is to bridge other identity federations (eduGAIN, institutional IdP) with the EGI AAI • Technical bridge: credentials translation, support in the middleware for other AuthN protocols • Policy bridge: build trust between SP and IdP, enable different level of trust

  7. Extend federated AuthZ • Provide tools to the users to manage their user communities • Distributed Attribute Authorities connected with the user’s IdPs • Can be used also within application-specific environments for user authorization • Maintain uniform authorization across multiple service providers • Based on the attributes provided by the user communities • Apply the collaborative trust approach of EGI to new authentication technologies

  8. Enable interoperability • E-infrastructures should collaborate in this evolution process • Enable SSO for users who has access to multiple infrastructures • Enable a European Authentication and Authorization Infrastructure that can be used by multiple resource federations and application specific frameworks
