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 identify a data item to be stored in the storage system, and to generate a data encryption key for the data item as a function of a first secret key and the data item. For example, the function may comprise hashing at least the data item. The client device is further configured to encrypt the data item using the data encryption key for the data item, and to send the encrypted data item to the storage system for storage therein. The client device in some embodiments is further configured to encrypt the data encryption key using a second secret key, and to send the encrypted data encryption key to the storage system for storage therein as metadata of the data item.
