ABSTRACT:
A supplier device 70 which supplies title data is equipped with a encryption module 74 for performing an encryption which is substitutive in nature and the user device 90 which uses the title data is equipped with a decryption module 93 for performing a decryption which corresponds to the encryption. The supplier device 70 uses this encryption module 74 to prove its own authorization and authenticate other devices. Similarly, the user device 90 uses this decryption module 93 to prove its own authorization and authenticate other devices.
