Blockchain construction method for distributed identity authentication in industrial field

Abstract

The invention discloses a blockchain construction method for distributed identity authentication in the industrial field, and the method comprises the steps: recording an identity authentication auditing identifier of an industrial entity at an authentication institution end into an identifier analysis system; carrying out authentication and credit endorsement of the industrial entity digital identity by an authentication authority (e.g., government, enterprise, etc.), with the authentication and endorsement being done prior to the industrial entity chaining; allocating a blockchain address ofeach industrial entity in an industrial network based on an identifier recorded by the industrial entity at an authentication mechanism end, registering the industrial entity on a blockchain according to a specific address, and preparing to perform an uplink operation, thereby protecting the digital identity of the industrial entity from being influenced by other equipment; after chaining, carrying out credible authentication of industrial entity digital identity information based on a digital identity authentication system of the block chain; the digital identity authentication system basedon the block chain guarantees the authenticity of digital identity information and provides credible authentication service.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain construction method for distributed identity authentication in the industrial field. Background technique [0002] In the 21st century, the Internet, new energy, new materials and biotechnology are rapidly forming huge industrial capabilities and markets, raising the entire industrial production system to a new level, promoting a new industrial revolution, and bringing human society into Industry 4.0 In this era, the core of Industry 4.0 is the deep integration of industrial fields represented by manufacturing and cyber-physical systems.
