Distributed chain type data sharing authorization method based on time sequence and encryption

Abstract

The invention discloses a distributed chain type data sharing authorization method based on time sequence and encryption, and relates to the field of computer data exchange, in particular to the safety fields of data passwords, discrete algorithms, data transmission and access. According to the distributed data sharing and consensus method, data blocks can be combined into a chain type data structure in a sequential connection mode according to the time sequence, and tamper-proof and forgery-proof distributed data sharing and consensus can be guaranteed in a cryptographic mode. According to the method, the data and contract are recorded along time, and the data and the contract can only be read and written and cannot be modified and deleted. The system has the advantages of safety, transparency and high efficiency in the application level and technology, so that the development of standard data exchange is particularly facilitated, and the popularization and innovation of the Internetof Things and sharing economy are promoted.

Description

technical field [0001] The invention relates to the field of computer data exchange, especially the security field of data cipher, discrete algorithm, data transmission and access. Background technique [0002] There are thousands of various data interfaces used by the unit's internal IT system and network elements, but the structure belongs to the traditional data request and response, and the performance is limited by the interface method (socket, WebService, etc.). The traditional data interface is only responsible for generating data, how to use data safely and effectively, how to share data safely, how to manage data, prevent data tampering, forgery and other issues cannot be solved, and as the business changes, the interface needs to be modified repeatedly, and even form technical business barriers , hindering business development. For the outside of the unit, the operational data cannot be safely traded and cannot generate value. Therefore, it is urgent to break thro...

Problems solved by technology

The traditional data interface is only responsible for generating data, how to use data safely and effectively, how to share data safely, how to manage data, prevent data tampering, forgery and other issues cannot be solved, and as the business changes, the interface needs to be modified repeatedly, and even form technical business barriers , hinder the development of business

For the outside of the unit, the operational data cannot be safely traded and cannot generate value. Therefore, it is urgent to break through the existing structure and mechanism, and provide a universal system that can ensure data authenticity, tamper-proof, distributed, authorized, smart contracts, and consensus Data sharing exchange method
