International Journal of Electronic Governance (IJEG), Vol. 8, No. 1, 2016

Abstract: We consider the problem of handling digital identities within service-oriented architecture (SOA) architectures. We explore federated, single sign-on (SSO) solutions based on identity managers and service providers. After an overview of the different standards and protocols, we introduce a middleware-based architecture to simplify the integration of legacy systems within such platforms. Our solution is based on a middleware module that decouples the legacy system from the identity-management modules. We consider both standard point-to-point service architectures, and complex government interoperability frameworks, and report experiments to show that our solution provides clear advantages both in terms of effectiveness and performance.
