Authentication and Authorisation for Research Collaboration Technical Revision to Enhance Effectiveness

协作和资源共享对研究至关重要。身份验证和授权基础设施（aai）在支持对资源的联合互操作访问方面发挥着关键作用。AARC技术修订以提高效率（AARC TREE）项目采用成功的、全球公认的“研究合作认证和授权”（AARC）模式及其旗舰成果——AARC蓝图架构（BPA），作为推动研究基础设施下一阶段整合的基础：扩展联邦访问管理以集成以用户为中心的技术、扩展对联邦数据和服务的访问（授权）、整合现有容量并避免碎片化和不必要的重复。AARC TREE项目的主要目标是：(i)捕获和分析新的认证和授权互操作性需求（作为支持跨主题领域集成用例的新兴需求），并提供AARC TREE中所表示的RIs中的aai服务（包括差距）的景观分析（ii）定义和验证解决RIs用例的AARC BPA的新技术和政策指南。这将改善RIs跨主题领域的整合，提高RIs支持新出现需求的能力（iii）通过提供验证环境和工具包，扩大能够实施AARC BPA和/或AARC指南的研究团体的数量。同时，支持现有的AARC社区采用新的指导方针。（iv）将RIs、电子基础设施和相关利益相关者聚集在一起，协调战略，整合新技术，更好地互操作和跨主题领域共享资源，并为不同的利益相关者制定纲要和建议

Collaboration and sharing of resources is critical for research. Authentication and Authorisation Infrastructures (AAIs) play a key role in enabling federated interoperable access to resources. 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 accessto federated data and services(authorisation), consolidating existing capacities and avoiding fragmentation and unnecessary duplication. The main objectives of the AARC TREE project are to: (i) 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 (ii) 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 (iii) 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 (iv) 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
