Since 2017, the Worldwide LHC Computing Grid (WLCG) has been working towards enabling token-based authentication and authorization throughout its entire middleware stack. Following initial publication of WLCG Token Schema v1.0 in 2019, OAuth2.0 token workflows have integrated across grid middleware. There are many complex challenges to be addressed before can end-to-end token-based, including not just technical hurdles but also interoperability with wider landscape. This paper presents...
The WLCG Authorisation Working Group was formed in July 2017 with the objective to understand and meet needs of a future-looking Authentication Infrastructure (AAI) for experiments. Much has changed since early 2000s when X.509 certificates presented most suitable choice authorisation within grid; progress token based identity federation provided an interesting alternative notable advantages usability compatibility external (commercial) partners. need interoperability this new model is...
Since 2017, the Worldwide LHC Computing Grid (WLCG) has been working towards enabling token based authentication and authorisation throughout its entire middleware stack. Following publication of WLCG Common JSON Web Token (JWT) Schema v1.0 [1] in 2019, developers have able to enhance their services consume validate JWT-based [2] OAuth2.0 [3] tokens process authorization information they convey. Complex scenarios, involving multiple delegation steps command line flows, are a key challenge be...
