摘要： PROBLEM TO BE SOLVED: To prevent illegal copy of information. SOLUTION: An EEPROM 27 of a DVD player 1 as a source stores a hash function and a service- key. An EEPROM 50 of a personal computer 2 as a sink stores the ID and license0 key. A DVD player 1 requests an ID from the personal computer 2 (S1). At the time of receiving the ID, the DVD player 1 applies a hash function to data (ID ||service- key) obtained by connecting the ID with the service- key, and obtains a key lk. Moreover, the DVD player 1 generates a cryptographic key (sk), and transmits data (e) obtained by enciphering with the key (lk) as a key to the personal computer 2 (S8). The personal computer 2 decodes the encoded data (e) by using the license- key as a key, and obtains a cryptographic key (sk') equal to the cryptographic key (sk).

摘要： PURPOSE:To reduce the traffic volume of a bidirectional bus, to improve the transmission efficiency and to simplify communication procedures. CONSTITUTION:A microprocessor 12 of a TV 10 inserts HDOPR, which discriminates a frame for command, a frame for request, a frame for answer, and a frame for status automatic transmission, to data #2 of a data field to form a transmission signal and transmits this transmission signal to a VTR 20 through a bidirectional bus 1. A microprocessor 22 of the VTR 20 detects HDOPR from the transmission signal and recognizes the classification of the received frame based on this HDOPR.
