Introducing a Dynamic Federation Model for RESTful Cloud Storage

This paper presents a solution for RESTful cloud storage in a dynamic identity federation. With dynamic federa- tions, Cloud Service Providers are able to find Identity Providers autonomously in the cloud in order to make services flexible, scalable and interoperable. By combining a Representational State Transfer architecture with SAML-based identity federation, a distributed and decentralized cloud storage is provided which allows users to access files via the Internet seamlessly and transparently.
