GridFTP传输和相应的网格安全基础设施 (GSI)的认证和授权系统进行了数据传输 全球大型强子对撞机计算网格(WLCG)的支柱, 十年然而,在2017年,对Globus Toolkit的支持结束-参考 这些技术的平台-宣布。这重新激发了 并加大力度取代这些支柱。我们提出了一个端到端的替代方案 利用基于HTTP的WebDAV作为传输协议, 分布式授权 这个替代生态系统,整合了重要的预先存在的工作和想法, 该地区,坚持共同的行业标准,以最大限度地可能, 最小限度地对核心进行商定的扩展或共同解释 协议.不记名令牌方法允许资源提供者委托授权 决定LHC实验的实验专用存储 地区 此演示涉及整个堆栈-从多个存储 将FTS 3的元素实现应用到Rucio数据管理系统。我们 展示了如何利用 不记名令牌,无需使用GSI代理证书进行存储 交互.
GridFTP transfers and the corresponding Grid Security Infrastructure (GSI)-based authentication and authorization system have been data transfer pillars of the Worldwide LHC Computing Grid (WLCG) for more than a decade. However, in 2017, the end of support for the Globus Toolkit - the reference platform for these technologies - was announced. This has reinvigorated and expanded efforts to replace these pillars. We present an end-to-end alternate utilizing HTTP-based WebDAV as the transfer protocol, and bearer tokens for distributed authorization. This alternate ecosystem, integrating significant pre-existing work and ideas in the area, adheres to common industry standards to the fullest extent possible, with minimal agreed-upon extensions or common interpretations of the core protocols. The bearer token approach allows resource providers to delegate authorization decisions to the LHC experiments for experiment-dedicated storage areas. This demonstration touches the entirety of the stack - from multiple storage element implementations to FTS3 to the Rucio data management system. We show how the traditional production and user workflows can be reworked utilizing bearer tokens, eliminating the need for GSI proxy certificates for storage interactions.
