Dynamic ID based RFID verification method and system

Abstract

The invention comprises a dynamic ID based RFID verification method. The method is characterized by comprising the realization steps that S1) a reader sends an authentication request, and the authentication request is completed; S2) a label makes response feedback in response to the authentication request; S3) a background database is used to verify authentication preliminarily; and S4) the label is used for verify authentication secondarily. The method and system have the advantages that use of formula encryption can ensure that private content is safe and eavesdropping and position tracking are prevented; use of double-randomized-number verification can prevent playback attack effectively; neither an invalid card reader nor an invalid label can pass validity authentication, invalid reading, counterfeiting attack and disguising can be prevented effectively; and due to a formula is simple, neither too high computing capability nor too much storage space is needed, and the manufacture cost is not increased.

Description

technical field [0001] The invention relates to the field of computer information technology, in particular to a dynamic ID-based RFID verification method and system. Background technique [0002] With the development of informatization and the Internet of Things in today's society, the application of RFID is becoming more and more extensive, but the security risks of RFID are also becoming more and more prominent. The security of RFID is mainly restricted by two reasons: [0003] The first is that the communication between the RFID electronic tag and the card reader is transmitted through radio frequency signals, and the transmitted information is all exposed to the outside, and the privacy of the data cannot be well protected. [0004] The second is that the limited computing power and small storage space of RFID electronic tags have brought greater difficulties to the security design of RFID systems. [0005] The specific security issues faced by RFID systems mainly inc...

AI Technical Summary

Problems solved by technology

[0003] The first is that the communication between the RFID electronic tag and the card reader is transmitted through radio frequency signals, and the transmitted information is all exposed to the outside, and the privacy of the data cannot be well protected.

[0004] The second is that the limited computing power and small storage space of RFID electronic tags have brought greater difficulties to the security design of RFID systems.

[0007] The physical mechanisms mainly include: Faraday cage, blocker label, active interference, button label, crop label technology, elimination of label data, frequency modulation communication technology, but these physical methods add additional physical equipment and original parts, which are extremely inconvenient to use. Increased manufacturing and usage costs

[0008] The security mechanisms based on cryptographic technology mainly include: Hash lock protocol, Hash chain protocol, HSAP protocol, etc. These methods either cannot effectively prevent illegal reading, camouflage and spoofing, etc., or require too high computing power and storage space, resulting in RFID tags The manufacturing cost has been greatly increased
