摘要：An object of the invention is to prevent original high quality contents data from

being illegally obtained by extracting encryption breaking information from datatransmitted through a single signal line for connecting two apparatuses and by using theencryption breaking information to decrypt encrypted contents data. In a contents datatransmission/reception system, a contents data transmitter encrypts contents data byusing key information, transmits the key information through plural signal lines to acontents data receiver, and then, transmits the encrypted contents data through theplural signal lines to the contents data receiver. The contents data receiver acquires thekey information from data transmitted from the contents data transmitter through theplural signal lines, receives the encrypted contents data transmitted from the contentsdata transmitter through the plural signal lines, and decrypts the encrypted contentsdata by using the key information.
