Industrial Internet data security management system and method based on blockchain

Abstract

The invention relates to an industrial Internet data security management system and method based on a blockchain, and aims to solve the problem that an existing data security management mechanism cannot well meet the requirements of security, management and performance in an industrial Internet application scene. The invention provides a data security management mechanism and system based on a blockchain technology in an industrial Internet environment. The blockchain is used as a trusted third party to realize security transmission, authentication, traceability and the like of industrial data. Specifically, a permission chain is adopted as a bottom layer system, and a data storage format and access control schemes of users at all levels are defined on the basis of the permission chain, and the permission chain comprises permission definition and change schemes and corresponding execution processes of off-chain data verification and on-chain data hierarchical access. The industrial data security management system is composed of two parts: a blockchain-based industrial data security management system function module design and a system operation process.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a blockchain-based industrial Internet data security management system and method. Background technique [0002] In the traditional Internet, commonly used data security mechanisms include the method of using various encryption algorithms to encrypt data before transmission, and the method of restricting the visible range of data through access authority classification. For the data encryption transmission mechanism, the data is encrypted mainly through common data encryption algorithms such as MD5 algorithm and SHA1 algorithm, and decrypted after the transmission is completed to realize secure transmission; for the access authority classification mechanism, it is mainly through group management -The control process assigns and judges user permissions to achieve hierarchical security access to data. [0003] The Industrial Internet is an industry and applica...
