Abstract
An apparatus in an illustrative embodiment comprises a client device configured for communication with a storage system, with the client device comprising a processor coupled to a memory. The client device is further configured to generate a data encryption key for a data item by computing a function of at least the data item, to encrypt the data item using the data encryption key for the data item, to encrypt the data encryption key using a secret key of the client device, and to send the encrypted data item and the encrypted data encryption key to the storage system for storage in the storage system. The client device is still further configured to retrieve the encrypted data item and the encrypted data encryption key from the storage system, and to perform an integrity check on the retrieved encrypted data item using a result of decrypting the retrieved encrypted data encryption key.
