Abstract: Backup data in a single-instance storage device is accessed through a backup server using hashes representative of and pointing to the backup data. To prevent unauthorized access, the server provides each client with encrypted versions of hashes corresponding to data backed up by the client. The hashes can be encrypted using client-specific symmetric encryption keys known to the server. To request data, a client provides the backup server with a corresponding encrypted hash. The backup server decrypts the encrypted hash using the client's encryption key. The original hash is only obtained if the key used for decryption is identical to the key used for encryption. Consequently, if an encrypted hash is stolen or otherwise acquired by a client different from the client that backed up the corresponding data, it cannot be used by the different client to request the corresponding data from the backup server.
