Embodiment Construction

[0026] In order to make the technical problems, technical solutions and effective results to be solved by the present invention clearer, the present invention will be further elaborated below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0027] see figure 1 , a method for realizing aerospace data cross-network traceability based on blockchain cross-chain technology. The method uses two systems of business system and cross-chain system to realize aerospace data cross-network traceability. Among them, the business system includes data application area, data service area, cross-network transmission equipment, and middleware between the two network areas and the cross-network transmission equipment, which mainly realizes the query of catalog data and the cross-network transmi...

Abstract

The invention provides an aerospace data cross-network tracing method based on a block chain cross-chain technology, and belongs to the technical field of aerospace data tracing. According to the method, in a mode of combining 'on-chain and off-chain', aerospace data catalogues are inquired in an off-chain service system, user permissions are approved, and aerospace data are transmitted in a cross-network manner; and the on-chain cross-chain system adopts an asymmetric encryption technology to encrypt order information and protect user privacy, adopts a relay chain mode to carry out cross-chain transmission on the encrypted order information, records the order information and an order approval result on a chain, calls an intelligent contract to query information on the chain, and realizes cross-network tracing of spaceflight data.

Description

technical field [0001] The invention belongs to the technical field of aerospace data traceability, in particular to a cross-network traceability method for aerospace data based on blockchain cross-chain technology. Background technique [0002] At present, aerospace data is scattered and stored in different networks that are physically isolated. Although there are ways to obtain data and data traceability in their respective networks, it is difficult to achieve aerospace data traceability between physically isolated networks. In order to effectively grasp the data flow, realize data asset management, and improve the application efficiency of aerospace data, a method that can trace the origin of aerospace data between physically isolated networks is urgently needed. [0003] The Chinese patent with publication number CN109657424A discloses a method for copyright management of remote sensing results based on blockchain. By distributing and storing remote sensing results in t...
