Industrial Internet identifier analysis access control method based on block chain

Abstract

The invention discloses an industrial Internet identifier analysis access control method based on a block chain. Relevant information of each identifier in the industrial Internet is stored in a target block chain in advance, and the method comprises the steps of verifying whether a user has an access permission or not according to an intelligent contract under the condition of receiving an analysis request of the user for a to-be-accessed identifier; if yes, obtaining mapping information of the to-be-accessed identifier, and calculating a to-be-accessed hash value of the mapping information;comparing the hash value to be accessed with the hash value stored on the target block chain; and if the comparison is successful, sending the mapping information of the identifier to be accessed to the user. According to the method, each identifier is stored in the target block chain, so that credibility of identifier resources is ensured, and whether a user has access permission or not is verified according to the smart contract; if yes, comparing the hash value to be accessed with a hash value stored on the target block chain; and if the comparison is successful, sending the mapping information of the identifier to be accessed to the user, so that distortion of an analysis result is avoided.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based industrial Internet identification analysis access control method. Background technique [0002] As the "central nerve" of the Industrial Internet, the Industrial Internet logo analysis system is an important part of the Industrial Internet network architecture. It provides coding and registration for physical resources such as industrial equipment, machines, materials, parts and products, and virtual resources such as algorithms and processes. It is the premise and basis for realizing the precise connection between the global supply chain system and the enterprise production system, product life cycle management and intelligent services. my country actively deploys the construction of global root nodes, auxiliary root nodes, national top-level nodes, and second-level nodes for logo analysis. The number of industrial Internet logos can reach hundreds of b...
