Abstract: A data transfer method for preventing the malfunction of the conventional equipment which does not cope with encipherment at the time of transmitting enciphered AV information protected by a copyright through an IEEE 1394 bus. In the method, cipher identification information indicating the state of encipherment of a real data part and the real data part are contained in synchronous data transferred through isochronous communication and encipherment is effected only on the real data part. According to this method, a transmitter transmits cipher identification information indicating the state of encipherment of the real data part contained in the synchronous data together with real data and a receiver which detects the fact that the real data part has been enciphered from the cipher identification information requests the transmitter to send deciphering information and, upon receiving this information from the transmitter in response to the request, deciphers the real data part by using the deciphering information.

Abstract: A data transmitting and receiving method for improving transmission and reception efficiency can be obtained by improving the security through update of a control key and reduction of the frequency of the authentication and key exchange process. An STB 1 transmits encrypted digital data Kw (D) obtained by encrypting digital data D using a work key Kw, and an encrypted work key Kc (Kw) obtained by encrypting the Kw using a control key Kc. The Kc is periodically or non-periodically updated, and an identifier L identifying the Kc is assigned to each Kc. A VTR device 2 decrypts the received Kc (Kw) using the Kc obtained by performing the authentication and key exchange process with the STB 1, decrypts the Kw (D) received using the Kw to obtain the D. It is determined whether or not the Kc has been updated while the reception process is suspended by referring to the transmitted L when the reception process is suspended and then resumed. If it is determined that the Kc has been updated, then the authentication and key exchange process is performed again to obtain the updated Kc.

Abstract: A data transfer method which eliminates erroneous operation of conventional devices not supporting encryption when copy-protected AV information is encrypted and sent on the IEEE 1394 bus. Synchronous data transferred through isochronous communication contains i) encryption identification information for indicating encryption of actual data and ii) actual data. Only the actual data is encrypted. Encryption identification information indicating encryption status of actual data in synchronous data is sent together with actual data from the sending device. A receiving device detecting encryption of actual data from this encryption identification information requests for decrypting information to the sending device. The receiving device decrypts the actual data using decrypting information received from the sending device according to this request.
