focus on the integration aspects of the blueprint architecture
provide recommendations and guidelines for implementers, service providers and infrastructure operators on implementing scalable and interoperable AAIs across e-infrastructures and scientific communities
work in close collaboration with the policy, pilots, and the training and outreach activities of AARC2
work on the evolution of the blueprint architecture, with a focus on identity provider / service provider (IdP/SP) proxies, scalable authorisation solutions for multi-service provider environments and other solutions for integrating with R&E federations and cross-sector AAIs

| AARC-JRA1.4A | Guidelines on expressing group membership and role information | Information about the groups a user is a member of is commonly used by SPs to authorise user access to protected resources. Apart from the group information that is managed by the user’s home IdP, research communities usually operate their own group managing services. Such services often act as Attribute Authorities, maintaining additional information about the users, including VO membership, group membership within VOs, as well as user roles. It is therefore necessary that all involved SPs and IdPs/AAs can interpret this information in a uniform way. Specifically, the following challenges are addressed by this document:

| AARC2-JRA1.1A | Guideline on the exchange of specific assurance information between Infrastructures | Increasingly Research Infrastructures and generic e-Infrastructures compose an 'effective' assurance profile derived from several sources. The assurance elements may come from an institutional identity provider (IdP), from community-provided information sources, from step-up authentication services, and from controls placed upon the user, the community, or the Infrastructure Proxy through either policy or technical enforcement. Knowledge about the upstream source of either identity or authenticator can also influence the risk perception of the Infrastructure and result in a modification of the assurance level, e.g. because it has involved a social identity provider or perhaps a government e-ID. The granularity of this composite assurance profile is attuned to the risk assessment specific to the Infrastructure or Infrastructures, and is often both more fine-grained and more specific than what can reasonably be expressed by generic IdPs or consumed by generic service providers. Yet it is desirable to exchange as complete as possible the assurance assertion obtained between Infrastructures, so that assurance elements need not be re-asserted or re-computed by a recipient Infrastructure or Infrastructure service provider. This document describes the assurance profiles that are recommended to be used by the e-Infrastructures and research infrastructures AAI platforms to exchange user authentication information between infrastructures. |

Forced reauthentication can therefore provide additional protection for sensitive resources. |
