Public Key Infrastructure (PKI) information, including publicly available certificates and digital signature keys, and / or corresponding payment information, if the return content is pre-paid over a wired network. .

Accordingly, in the validity authentication process for the return content information, the broadcast receiving unit 155 on the digital broadcast receiving system 150 returns the corresponding digital broadcast system 100 (eg, a return channel network) to be included in the return content. This is a process of authenticating validity of the returned content address, access authority information, copyright information, PKI information, and / or payment information.

If the return access code generator 410 fails to authenticate the validity of the return content information (525), the return access code generator 410 returns the content to the digital broadcasting system 100 from the wired network through a smart card. End of the process of generating a return access code to share and / or interwork with the included and / or stored in the ICC storage information provided in the smart card.

On the other hand, if the return access code generation unit 410 authenticates the validity of the return content (530), the return access code generation unit 410 is the broadcast receiving unit 155 on the digital broadcast receiving system 150, the corresponding digital broadcasting system In operation 535, the method determines whether the return additional information other than the return content information is required in the process of accessing the return content and receiving the return content service.
