Zusammenfassung
Federated Identity Management is an effective technology that allows multiple organizations to share resources. Deployments of the protocol Security Assertion Markup Language (SAML) practically require the pre-exchange of aggregated metadata files, making federations to fixed trust boundaries. Dynamic metadata exchange between identity provider and service provider via a trusted third party (TTP) overcomes these barriers. In this paper, we contrast dynamic metadata exchange with other state-of-the-art approaches and present the topology of the dynamic metadata exchange via a TTP. Furthermore, a distributed dynamic metadata exchange is proposed, in order to enhance the current protocol and provide a scalable solution for large-scale infrastructures.
