As the volume of digital data rapidly increases, storage clouds are becoming a popular solution for both enterprise and personal data, and the number of storage cloud solutions is also increasing. However, these solutions do not yet deal with the need of customers for interoperability and data migration from one cloud to another. These issues can be addressed through federation of cloud infrastructures. An important aspect of federation is delegation of access control, where one actor, e.g., an end user, authorizes another actor, e.g., a cloud provider, to act on its behalf, typically with a subset of its access rights, safely and securely.
