Method and device for generating and verifying anti-counterfeit electronic tag based on CPK (Combined Public Key)

Abstract

The invention discloses a method and a device for generating and verifying an anti-counterfeit electronic tag based on a CPK(Combined Public Key). The generation method comprises the following steps: combining a UID (Unique Identifier) of an RFID (Radio Frequency Identification Device) with parameter information of a carrier of the RFID to generate anti-counterfeit information; signing the anti-counterfeit information according to a preconfigured private key to generate an anti-counterfeit information signature; writing the anti-counterfeit information signature and the parameter information into the RFID to generate the anti-counterfeit electronic tag. The verification method comprises the following steps: operating CPK anti-counterfeit tag verification software in an NFC (Near Field Communication) device, reading anti-counterfeit information and signature information in the tag by using an NFC communication protocol, judging authenticity and integrity of the anti-counterfeit information by a PCK signature verification protocol so as to implement true and false identification of the carrier. By virtue of the method and the device for generating and verifying an anti-counterfeit electronic tag based on the CPK, the unique physical characteristic of the RFID and the integrity of logic information are organically combined, and a novel anti-counterfeit technique is implemented; the verification convenience is implemented by using the NFC technique; the method and the device have far-reaching influence on the popularization of the anti-counterfeit technique.

Description

technical field [0001] The present invention relates to the generation and verification technology of anti-counterfeit labels, specifically, to a method and device for generating and verifying anti-counterfeit electronic labels based on CPK (Combined Public Key, combined public key). Background technique [0002] For a long time, counterfeit and shoddy goods have not only seriously affected the economic development of the country, but also endangered the vital interests of enterprises and consumers. In order to protect the interests of enterprises and consumers and the healthy development of the market economy, the country and enterprises spend a lot of manpower every year And financial resources are used for anti-counterfeiting and anti-counterfeiting. [0003] At present, in the field of anti-counterfeiting, there is a trend of using electronic technology to prevent counterfeiting, especially the application of RFID (Radio Frequency Identification, radio frequency identifi...
