Abstract

Service-oriented architecture (SOA) will form the basis of future information systems. Web services are a promising way to implement SOA enabling the loose coupling of functionality at service interfaces. The focus in SOA changes from traditional software systems to reusable, business-relevant services. Considering the cross-cutting concern of identity management (IdM), it is still an open issue how to construct an SOA-aware IdM architecture enabling “identity as a service” and how to loosely couple the IdM services with SOA’s core concern part. In this paper we present a blueprint for a service-oriented identity management architecture featuring interoperability by applying existing standards. Our solution has been tested and evaluated in an implementation case study.KeywordsAccess ControlAccess Control ModelSimple Object Access ProtocolPolicy Decision PointPolicy Enforcement PointThese keywords were added by machine and not by the authors.
