Abstract: Secure shared access to encrypted data in a data store is facilitated by using a data control server (DCS) to maintain a data storage reference table (DSRT) for shared data units present in a shared data pool hosted by least one data storage device, and accessible to a plurality of computing entities. The DSRT specifies for each shared data unit identifier information, location information for accessing the shared data unit in the shared data pool, and a hash value which has been computed for the shared data unit. The DCS selectively facilitates a decryption operation by providing hash values which serves as a basis for deriving a decryption key for decrypting shared data units which have been identified.

Abstract: Systems and methods for operating a cloud based computing system. The methods comprise: receiving, by a cloud server, a request for accessing Virtual Hard Disk (“VHD”) data associated with a first location in the VHD of a Virtual Machine (“VM”) hosted by a remote computing device; extracting, by the cloud server, at least a first address specifying the first location from the request; translating, by the cloud server, the first address into a second address specifying a second location in a cloud storage where the VHD data is stored; and communicating from the cloud server the second address to the remote computing device for facilitating access to the VHD data stored in the cloud storage.
