Abstract: A system, method, and computer-readable storage medium for protecting a set of storage devices using a secret sharing scheme. The data of each storage device is encrypted with a key, and the key is encrypted based on a shared secret and a device-specific value. Each storage device stores a share and its encrypted key, and if a number of storage devices above a threshold are available, then the shared secret can be reconstructed from the shares and used to decrypt the encrypted keys. Otherwise, the secret cannot be reconstructed if less than the threshold number of storage devices are accessible, and then data on the storage devices will be unreadable.
