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. Multiple manager device records each comprise a first key identical for each of the records, and a second key that different for each of the records. The controller generates an authorization request using the first key and receives a response to the request generated by a manager device. The response is specific to that manager device. The controller uses the response to locate the record; decrypts the located manager device record to obtain key data; and generates configuration data based on the key data to register the device.
