Privacy, security, and trust concerns are continuously hindering the growth of cloud computing despite its attractive features. To mitigate these concerns, an emerging approach targets the use of multi-cloud architectures to achieve portability and reduce cost. Multi-cloud architectures however suffer several challenges including inadequate cross-provider APIs, insufficient support from cloud service providers, and especially non-unified access control mechanisms. Consequently, the available multi-cloud proposals are unhandy or insecure. This paper proposes two contributions. At first, we survey existing cloud storage provider interfaces. Following, we propose a novel technique that deals with the challenges of connecting modern authentication standards and multiple cloud authorization methods.
