Authentication and Authorisation for Research Collaboration Technical Revision to Enhance Effectiveness


Coordinator: NORDUNET A/S
The AARC Technical Revision to Enhance Effectiveness (AARC TREE) project takes the successful and globally recognised “Authentication and Authorisation for Research Collaboration” (AARC) model and its flagship outcome, the AARC Blueprint Architecture (BPA), as the basis to drive the next phase of integration for research infrastructures: expand federated access management to integrate user-centring technologies, expand access to federated data and services (authorisation), consolidating existing capacities and avoiding fragmentation and unnecessary duplication.

EGI Foundation role in the project:

EGI Foundation leads the activities on Communication Dissemination and Exploitation Management and significantly contributes to the technical guidance and architecture definition, trust policy harmonisation and interoperability, validation activities, and to the preparation of the Compendium and recommendations.

Expected results:

The project aims to:

  • Capture and analyse new Authentication and Authorisation interoperability requirements (as emerging that support integration use-cases across the thematic area) and provide a landscape analysis of AAIs services (including gaps) in the RIs represented in AARC TREE
  • Define and validate new technical and policy guidelines for the AARC BPA that address RIs use-cases. This will improve the integration of RIs across thematic areas and increase the ability of RIs to support emerging needs
  • Expand the number of research communities that can implement the AARC BPA and/or the AARC guidelines, by providing a validation environment and toolkits. At the same time support existing AARC communities in adopting new guidelines
  • Bring RIs, e-Infrastructures and relevant stakeholders together to align strategies to integrate new technologies, better interoperate and share resources across thematic areas and produce a compendium and recommendations for different stakeholders

Relevance for EGI:

The participation in the project will help EGI offer cutting-edge AAI services, therefore maintaining the EGI Check-in up to date with the major technological developments in the AAI field.
