Method for guaranteeing uniqueness of digital certificate based on RFID (radio frequency identification device) technology

Abstract

The invention belongs to the technical fields of RFIDs (radio frequency identification devices), road traffic management and physical distribution management, and specifically relates to a technical method for the safety guarantee of a digital certificate based on an RFID technology. The method comprehensively uses RFID-curable IDs (identities), EPCs (electronic product codes) and other serial numbers as well as data encryption and digital signature algorithms, thereby guaranteeing the used RFID to be unique. The method can be used for various types of RFIDs which support read-write operation and can store user data, including active or passive RFIDs, HF (high frequency) or UHF (ultra high frequency) RFIDs and the like. The invention can enable the RFIDs used in the fields of road traffic management, physical distribution management and the like to have the capabilities of counterfeit prevention, reduplication prevention, falsification prevention, disavowal prevention and the like.

Description

technical field [0001] The invention belongs to the technical fields of RFID, road traffic management and logistics management, and in particular relates to a method for ensuring the uniqueness of a digital card. Background technique [0002] RFID electronic tags are one of the most critical components of the Internet of Things system. The information stored in RFID is the source of management information, and RFID also has a one-to-one correspondence with the managed objects. If there is a hidden danger of malicious forgery, copying, and tampering in RFID, the management system will lose its proper data foundation, which will bring disastrous consequences. [0003] RFID electronic tag technology has strong anti-counterfeiting capabilities, but in the face of attackers who master high-tech tools, it is not enough to rely solely on the read-write control and data encryption functions of RFID itself. For example, in the case of not decrypting encrypted data Under the circums...

Problems solved by technology

If the RFID has the hidden danger of being maliciously forged, copied, or tampered with, the management system will lose its due data foundation, which will bring disastrous consequences

[0003] RFID electronic tag technology has strong anti-counterfeiting capabilities, but in the face of attackers who master high-tech tools, it is not enough to rely solely on the read-write control and data encryption functions of RFID itself. For example, in the case of not decrypting encrypted data Under the current situation, counterfeiters copy a large number of counterfeit electronic tags by copying data, which will instead make anti-counterfeiting labels a "legal cloak" for counterfeiting and selling

[0004] Therefore, how to ensure the uniqueness of the stored content of the RFID electronic tag is very necessary, otherwise the anti-counterfeiting effect will be greatly weakened, or even completely lost
