RFID TAG ISSUE SYSTEM AND METHOD, RFID TAG AUTHORIZATION SYSTEM AND METHOD

摘要

A system and a method for issuing an RFID(Radio Frequency IDentification) tag, and the system and the method for authenticating the RFID tag are provided to authenticate that the RFID tag is issued by a right CA(Certificate Authority) by recording authentication information to a tag memory in an RFID tag issuance process, and using the authentication information when the RFID tag is recognized. An RFID tag issuance system(130) includes an authentication information generator and an RFID tag issuer. The authentication information generator generates authentication information to be stored in an RFID tag(150) by encoding a secret key assigned to an RFID service providing authority and a password to be stored in the RFID tag with a hash function algorithm. The RFID tag issuer generates a protocol control code and an error check code to be stored to the RFID tag, encodes the protocol control code and the error check code by using the generated authentication information, and stores the encoded codes to a memory of the RFID tag. The RFID tag issuer stores a result value of XOR operation of the protocol control code and the authentication information, and the result value of the XOR operation of the error check code and the authentication information in the memory of the RFID tag.
