Abstract
Disclosed herein is a data storage device. A data port transmits data between a host computer system and the data storage device. A non-volatile storage medium stores encrypted user content data and a cryptography engine connected between the data port and the storage medium uses a cryptographic key to decrypt the encrypted user content data. The access controller generates authorization request data indicative of multiple devices to be authorized, and stores the authorization request data on non-volatile configuration memory of the data storage device. Upon approval of the authorization request data by a manager device that is registered with the access controller as a manager device, the access controller locates the authorization request data of one of the multiple devices to be authorized and registers the one of the multiple devices to be authorized as an authorized device.
