ABSTRACT:
A hand-held token for secure conveyance of encryption keys includes memory for holding a media key and at least one device key. Control logic reads the media key from memory, encrypts the media key based on the device key, and transmits the encrypted media key to a data storage device. The data storage device decrypts the encrypted media key using its own device key, which may have previously been downloaded from a token.
