Abstract
A method performed by a client includes (i) receiving a lease from a tenant including a core including lease terms and an identification of the tenant and a first signature that cryptographically combines the core and a secret code associated with the tenant, the secret code being unknown to the client, (ii) sending a storage request to a central entity for access to remote storage including (a) a body including the core and an object identifier, which identifies an object stored in the remote storage and (b) a second signature that cryptographically combines the body and the first signature, and (iii) receiving a storage response including the object from the remote storage when (I) a computation performed by the central entity of the second signature based on the secret code, the core, and the body matches the second signature and (II) the storage request complies with the lease terms.
