Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The invention adopts the double anti-counterfeiting technology of PUF and digital signature, so that the RFID system can achieve lightweight authentication. The structure of the anti-counterfeiting device and its relationship with the RFID system are as follows: figure 1 shown. It consists of an ultra-high frequency (UHF) tag unit with a PUF module, a reader, a digital signature device and a background editor. Both the PUF module and the RFID tag are connected to the reader, and the other end of the reader is connected to the digital signature device and the background editor respectively,...

Abstract

The invention discloses an RFID anti-counterfeit device based on PUF (Physical Unclonable Functions) and digital signature, comprising a tag unit, an RFID reader, a signature unit and a background editor. The tag unit includes an RFID tag and a PUF module, which are connected with the RFID reader in a two-way mode. The other end of the reader is connected with the digital signature equipment and the background editor. The digital signature equipment and the background editor are connected at the same time. Light-weight authentication of an RFID system is realized. Lightweight tag operation is ensured. The computing cost of the whole system is controlled appropriately. The authentication efficiency is improved. The robustness, reliability and data integrity are enhanced. A feasible security guarantee is provided for further expansion of the public key cryptography technology in the RFID system.

Description

technical field [0001] The invention relates to the field of information security, in particular to an RFID (Radio Frequency Identification, radio frequency identification) anti-counterfeit device and verification method based on PUF (Physical Unclonable Functions) and digital signatures. Background technique [0002] RFID automatically identifies target objects through radio frequency signals. This identification process is non-contact, and items can be tracked and exchanged data quickly. The communication process does not require mechanical or optical contact between identification equipment and specific target objects. . RFID applications are divided into low frequency, high frequency, and ultra high frequency (Ultra High Frequency, UHF). Compared with tags in other frequency bands, UHF RFID has the advantages of long reading and writing distance, small size of tag, and fast reading and writing speed. Development prospects for applications. A basic RFID system generall...
