Towards Interoperabilty
in Identity Federation Systems Department of Communication and
Information Engineering , University of Murcia 30100 Murcia, Spain Abstract Digital services aimed at humans need to ensure user
identity. Governments and institutions confront the identity problem when migrating their face to face services to the digital
world, where no facial identification is plausible. On the other hand, users
concerns regarding their privacy and security are a barrier to be overcome
during the migration. Identity federations are envisioned to unify and
simplify user and service management through trust relationships. Recent
trends indicate that federations are limited by target audiences and scope
and are isolated from each other. It is necessary to go one step further and
work in interoperability mechanisms to develop the existing federations and
improve user experience and service quality. This work reviews some of the
most important identity federations, with the focus on well
defined sectors such as research and education communities and
governments, specifically Moonshot, eduGAIN, EUDAT,
STORK and EIDAS. Based on their analyses, we consider interfederation
scenarios between eduGAIN, STORK and eIDAS and propose interoperability mechanisms to reach interfederation solutions to extend the user’s scope of
each o with the others and thus provide wider federation possibilities. Keywords: Identity Federation, AAI,
