Abstract
Prevent fraudulent copies.
The data encrypted by the 1394 interface 26 of the DVD player 1 is transmitted to the personal computer 2 and the magneto-optical disk device 3 via the 1394 bus 11. In the magneto-optical disk device 3 whose function is not open to the user, the received data is decoded by the 1394 interface 36. In contrast, in the personal computer 2 in which the function change is open to the user, the encrypted data is decrypted using the time-varying key i in the 1394 interface 49, and the decryption result is transferred in the application unit 61. Decryption is further performed using the session key (S).
