RFID TAG, RFID BACK END SYSTEM AND AUTHENTICATION METHOD FOR RFID

摘要

PURPOSE: An RFID(Radio Frequency ID) tag, and the RFID back-end systems and RFID authentication method thereof are provided to reduce operation load in the RFID tag by performing authentication in the RFID back-end system. CONSTITUTION: A random code generator(410) generates an encoded random code. A transceiver(420) transmits the encoded random code to an RFID reader. The transceiver receives authentication information, which is generated by using the encoded random code and unique ID information of the RFID code, of the RFID tag from the RFID reader. An authenticator(430) authenticates the RFID tag by using the authentication information of the RFID tag. If the RFID tag is authenticated, an authentication information generator(440) generates the authentication information of an RFID back-end system(400).
