ABSTRACT:
A generic access card is paired with a data destination device by insertion into its card slot, and the public portion of a public/private key is stored in the card. The card authenticates the destination device. The paired card is transported to a data source device which includes a card slot and a removable mass storage medium. The card, when inserted into the card slot of the data source and authenticated, transfers the public key to the source device. The source device generates content encoding keys, and encodes the data on the storage medium. The content encoding keys are encoded using the public key, and loaded onto the card. The card and the storage medium are transported to the destination device, where the card provides the encoded encryption keys. The destination device decodes the encrypted content encryption key(s) and decodes the encrypted data for playback or display.
