QAR data management method based on block chain technology

Abstract

The invention discloses a QAR data management method based on a block chain technology, and relates to the block chain technology and aviation information management. The architecture comprises a resource layer, a network layer and an application layer from bottom to top, in the network layer design, different organizations undertake different tasks, even if an identity authentication private key of a certain organization is leaked, only a certificate issued by an intermediate CA of the organization is influenced, and meanwhile, a more flexible and fine-grained sensitive data protection mechanism is adopted, so that the network performance is prevented from being influenced by coarse-grained modes such as channel isolation and the like; the resource layer corrects, divides and packages the data through a data processing module, an identity authentication mechanism of an identity management module ensures security of the data, and an IPFS is introduced to further reduce the network pressure of the blockchain; and the application layer directly faces users with different authorities under each organization to realize data sharing among the organizations. The problems of data fusion, equipment safety, information protection, multi-agent cooperation and the like in the construction process of the QAR data management system are effectively solved.

Description

technical field [0001] The invention relates to the fields of block chain technology and aviation information management, in particular to a QAR data management method based on block chain technology. Background technique [0002] The rapid development of modern civil aviation puts forward higher requirements for the security of aviation information storage. Aviation information storage technology, as an important means to ensure air traffic safety, has long been valued. In addition, effective data analysis based on massive aeronautical information to find out factors affecting aviation safety, and in-depth mining of the value behind the data have also attracted attention, but these are all based on the security and credibility of aeronautical information. [0003] Most of the traditional aviation information management methods can be classified into the following methods. One is to realize the safe storage of data. Each aviation enterprise builds a dedicated data management...
