Combining the X.509 and the SAML Federated Identity Management Systems

Abstract

Every distributed computing infrastructure requires authentication and authorisation infrastructures (AAI) to manage access to resources and content. Several of such so called AAI systems are in use within different groups of users. In the Large Scale Data Management and Analysis project we aim to support and bring together many user communities. We therefore need to harmonise the currently used AAI systems. The approach described is to translate between different authentication systems. We furthermore try to maintain the same trust level wherever possible, and to harmonise authorisation across the involved systems. © Springer-Verlag Berlin Heidelberg 2014.
