Abstract
Disclosed herein is a data storage device comprising a data path, an access controller, and a data store. The data path comprises a data port configured to transmit data between a host computer system and the data storage device; a non-volatile storage medium configured to store encrypted user content data; and a cryptography engine connected between the data port and the storage medium and configured to use a cryptographic key to decrypt the encrypted user content data stored on the storage medium in response to a request from the host computer system. The access controller is configured to store on the data store multiple entries associated with multiple respective registered devices. The multiple entries comprise authorization data indicative of cryptographic keys that selectively provide user access or manager access for each of the multiple registered devices.
