x509-free access to WLCG resources
/ Short, H (CERN) ; Manzi, A (CERN) ; De Notaris, V (CERN) ; Keeble, O (CERN) ; Kiryanov, A (CERN ; St. Petersburg, INP) ; Mikkonen, H (Helsinki Inst. of Phys.) ; Tedesco, P (CERN) ; Wartel, R (CERN)
Access to WLCG resources is authenticated using an x509 and PKI infrastructure. Even though HEP users have always been exposed to certificates directly, the development of modern Web Applications by the LHC experiments calls for simplified authentication processes keeping the underlying software unmodified.

Accessing data federations with CVMFS
/ Weitzel, Derek (Nebraska U.) ; Bockelman, Brian (Nebraska U.) ; Dykstra, Dave (Fermilab) ; Blomer, Jakob (CERN) ; Meusel, Ren (CERN)
Data federations have become an increasingly common tool for large collaborations such as CMS and Atlas to efficiently distribute large data files. Unfortunately, these typically are implemented with weak namespace semantics and a non-POSIX API. [...]

Securing Distributed Research
/ Short, Hannah (speaker) (CERN)
Global science calls for global infrastructure. A typical large-scale research group will use a suite of international services and involve hundreds of collaborating institutes and users from around the world. [...]

WLCG Authorisation from X.509 to Tokens
/ Bockelman, Brian (Unlisted, US) ; Ceccanti, Andrea (INFN, Italy) ; Collier, Ian (Daresbury) ; Cornwall, Linda (Daresbury) ; Dack, Thomas (Daresbury) ; Guenther, Jaroslav (CERN) ; Lassnig, Mario (CERN) ; Litmaath, Maarten (CERN) ; Millar, Paul (DESY) ; Sallé, Mischa (Nikhef, Amsterdam) et al.
The WLCG Authorisation Working Group was formed in July 2017 with the objective to understand and meet the needs of a future-looking Authentication and Authorisation Infrastructure (AAI) for WLCG experiments. Much has changed since the early 2000s when X.509 certificates presented the most suitable choice for authorisation within the grid; progress in token based authorisation and identity federation has provided an interesting alternative with notable advantages in usability and compatibility with external (commercial) partners.

Integrating a dynamic data federation into the ATLAS distributed data management system

/ATLAS Collaboration
Input data for applications that run in cloud computing centres can be stored at remote repositories, typically with multiple copies of the most popular data stored at many sites. Locating and retrieving the remote data can be challenging, and we believe that federating the storage can address this problem. [...]

The security model of the ALICE next generation Grid framework
/ Martinez Pedreira, Miguel (CERN) ; Grigoras, Costin (CERN) ; Yurchenko, Volodymyr (Natl. Acad. of Sci. of Ukraine) ; Melnik Storetvedt, Maksim (HVL, Norway)
JAliEn (Java-AliEn) is the ALICE next generation Grid framework which will be used for the top-level distributed computing resources management during the LHC Run 3 and onward. While preserving an interface familiar to the ALICE users, its performance and scalability are an order of magnitude better than the currently used framework. [...]
