The Authentication and Authorisation for Research and Collaboration (AARC) initiative was first launched in May 2015 to address the increased need for federated access and for authentication and authorisation mechanisms by research and e-infrastructures.
The first AARC Project ran between 2015 - 2017, where the first version of the AARC Blueprint Architecture and the initial set of guidelines was created.
A second phase of the project (AARC2) started in May 2017 to continue to develop and pilot an integrated cross-discipline authentication and authorisation framework, building on existing authentication and authorisation infrastructures (AAIs).
AARC TREE, Authentication and Authorisation for Research Collaboration Technical Revision to Enhance Effectiveness, started in March 2024 and will run until 2026.
