Block chain anti-counterfeiting transaction method supporting national cryptographic algorithm and computer equipment

Abstract

The invention provides a block chain anti-counterfeiting transaction method supporting a national cryptographic algorithm and computer equipment, and the method comprises the steps: enabling a background server to generate an initial block according to uploaded commodity information, carry out the hash calculation of the commodity information, obtain a first hash value, and store the first hash value in a block head; generating a node list corresponding to the commodity information in the initial block; in response to updating of the node list, acquiring latest node information in the node list and a public key corresponding to the node information; encrypting the commodity information and the latest node information by using a public key to obtain encrypted information; and issuing the encrypted information to an electronic tag, and enabling the electronic tag to enter a next node along with a commodity corresponding to the commodity information. According to the method, the trust problem between a front node and a rear node in the commodity circulation process and the commodity chaining problem are well solved, and the authenticity and reliability of the commodity and the commodity circulation process are ensured through encryption and decryption confirmation of the public key and the private key.

Description

technical field [0001] The invention relates to the application field of block chain technology, in particular to a block chain anti-counterfeiting transaction method and computer equipment supporting national secret algorithm. Background technique [0002] At present, the anti-counterfeiting methods of commodities are diversified, and it is usually judged whether the commodity is genuine according to whether the anti-counterfeiting code matches. Using the anti-counterfeiting code matching method to carry out anti-counterfeiting identification of goods, the anti-counterfeiting identification operation is usually carried out by the final consumer, and usually only one identification verification can be performed, ignoring the circulation of goods in the supply chain and among consumers Anti-counterfeiting issues in the process. [0003] With the advancement of technology, the difficulty of copying numbers, two-dimensional codes, lasers and special materials used to display a...

AI Technical Summary

Problems solved by technology

[0003] With the advancement of technology, the difficulty of copying numbers, two-dimensional codes, lasers and special materials used to display anti-counterfeiting codes is getting lower and lower, and the cost of counterfeiting is getting lower and lower, which makes the anti-counterfeiting of products more and more difficult, and the anti-counterfeiting effect increasingly ineffective
