  AARC (Authentication and Authorisation for Research Communities) is a
two-year EC-funded project to develop and pilot an integrated cross-discipline
authentication and authorisation framework, building on existing authentication
and authorisation infrastructures (AAIs) and production federated
infrastructure. AARC also champions federated access and offers tailored
training to complement the actions needed to test AARC results and to promote
AARC outcomes. This article describes a high-level blueprint architectures for
interoperable AAIs.
