PURPOSE: A radio-frequency identification(RFID) tag is provided to record identification(ID) information by including an encryption protocol in order to connect an encryption key and a key-index. CONSTITUTION: A memory unit(110) includes a saving region, in which ID information is saved, and the memory unit connects and saves an encryption key and a key-index. A receiving unit(120) receives a random number and the key-index from an RFID terminal. A data generating unit(135) searches a key-index which matches the received key-index from the memory unit and generates an authentication value which corresponds to the random number. The receiving unit transmits the authentication value to the RFID terminal. An authenticator(140) receives the encrypted ID information and the authentication value from the RFID terminal and generates an authentication value which corresponds to the ID information. |
