abstract = {Distributed data and compute infrastructures aim to provide
access to their data or compute services across disciplinary
and geographical borders to their users for scientific
research. The services are highly collaborative in nature
yet independent and shared among multiple scientific
communities. Information security and service discovery are
two essential functions and precursors for enabling such
research collaborations. Given the infrastructure’s
heterogeneity in data, compute, or other service offerings,
the services often require several kinds of authentication
protocols. Moreover, the users bring their own
organisational identity and relevant attributes to access
the infrastructure services. Should the services’
authentication protocol differ from that of the user’s,
the user may not be able to access the target service.
Therefore credential translation, attribute harmonisation,
scalable trust and authorisation policy management need to
be incorporated. In addition to that, enabling service
discovery in the federated infrastructures is crucial.
Proprietary service registration and query interfaces hinder
interoperability across infrastructures. Hence, instead of
proprietary and centralised registry approaches, a federated
and standard-based registry and discovery model is essential
for interoperability across the collaborating
infrastructures. This thesis is motivated by a case study
consisting of three multi-national research infrastructures:
compute (EGI), data management (EUDAT), and a community
infrastructure supporting linguistic research (CLARIN). The
thesis contributes EMIR, the European Middleware Initiative
(EMI) Registry, a decentralised service registry that
supports both hierarchical and peer-to-peer topologies and
enables collaboration in large-scale infrastructures. The
thesis also contributes the B2ACCESS service which
implements a proxy model with credential translation and
scalable trust and authorisation policy management. Finally,
the thesis contributes an integrative architecture realised
as a unified cross-infrastructure (or inter-federation)
service access framework, which bridges EMIR and B2ACCESS to
enable service discovery and access in federated
environments.},
