In order to prevent the USB set-top box from being duplicated by duplicating the unique ID 101, the smart card 100 generates and stores a unique key-SC 102 corresponding to the unique ID. Instead of directly transmitting the unique key-SC 102 to the outside, the encrypted key authentication code-SC 103, which performs its own operation using the unique key-SC 102, is generated and transmitted. The encrypted authentication code-SC 103 is a value that is changed every time as a result of performing an operation of the smart card itself. Therefore, since the encrypted authentication code-SC 103 is not transmitted, the USB set-top box can be prevented from being duplicated. The authentication server 700 for authenticating the USB set-top box also stores the unique key-CS (104) having the same value as the unique key-SC (102) stored by the smart card (100). In case of receiving 103, the encrypted authentication code-SC 103 can be authenticated using the unique key-CS104. That is, the authentication server 700 receives the encrypted authentication code-SC 103 from the smart card, stores the unique key-CS 104 which is the same key as the unique key-SC 102 stored in the smart card, and generates the unique key. -Authenticates the encrypted authentication code-SC (103) using the CS (104).
