Data security and confidentiality of RFID system
In addition to the data storage and transmission security of the background application system, the security of the entire RFID system should also focus on the following four aspects:
(1) The data security of the RFID electronic tag chip as an electronic license plate.
(2) Encryption and authorization of RFID electronic tags.
(3) Encryption and authorization of RFID reading and writing equipment.
(4) The legality verification of RFID electronic tags by RFID reading and writing equipment.
For the data security of the RFID electronic tag chip, it is necessary to comprehensively consider the division of labor and operation functions of the EPC area, TID area, USER area, and Reserved area. The data stored in the tag must be performed through the key and encryption algorithm generated by the key management system. Digital signatures and generation of access codes for accessing vehicle electronic tags. According to the definition, the scatter factor can use data in the EPC and TID areas, and determine whether the TID is customized by the manufacturer according to the model of the tag chip.
For the encryption and authorization of RFID reading and writing equipment, RFID electronic tags, and the former’s verification of the latter’s legitimacy, a key management system needs to be established, and a security authentication key card is issued to ensure that different key versions can be established. And define keys of different application types according to different functions or applications.
