A block chain-based data trading method for an aerospace TTC network

Abstract

The invention discloses a block chain-based data trading method for an aerospace TTC network. The method introduces the concept of user identity ID in the order management process, and ensures the user identity privacy through the mode of user information Hash. By constructing the transaction record block chain, the transaction record management is strengthened, which can effectively resist the malicious order attack from the third party, ensure the normal operation and scheduling of the tasks of the measurement and control business center to a certain extent, and at the same time, make the transaction records be queried and appealed. By constructing the data index block chain, the security of data transaction is enhanced, and the supervision of the transaction platform is formed, which makes the transaction platform unable to retain the data, ensures the security of the data, and also makes the transaction results undeniable for both parties, and provides evidence for the subsequent transaction traceability and complaint. By using the DRM copyright management technology to strengthen the protection of data copyright, the illegal copying and resale of of data are prevented.

Description

technical field [0001] The invention relates to the field of business operation of aerospace measurement and control network, in particular to a data transaction method of aerospace measurement and control network based on block chain. Background technique [0002] At present, the business operation of the aerospace measurement and control network is driven by user needs. The measurement and control business center arranges measurement and control tasks based on user needs, schedules the execution of tasks, and returns the final data results to users. At present, the business core of the aerospace measurement and control network is data transactions, but there are the following problems in the data transaction process: 1) There are risks such as data being copied and resold by a third party, and the rights and interests of data assets cannot be guaranteed. 2) The authentication and trust mechanism is not perfect, and the privacy of both parties to the transaction cannot be g...

AI Technical Summary

Problems solved by technology

At present, the business core of the aerospace measurement and control network is data transactions, but there are the following problems in the data transaction process: 1) There are risks such as data being copied and resold by a third party, and the rights and interests of data assets cannot be guaranteed

2) The authentication and trust mechanism is not sound, and the privacy of both parties to the transaction cannot be guaranteed. For example, the transaction information of both parties is not encrypted, so the user information of the purchased data is easily known by the data provider or other third parties, resulting in the leakage of user privacy

3) Transaction records are easy to be tampered with, and transaction validity is difficult to prove

4) After the data transmission is completed, if there is a transaction disagreement or denial, it will make it difficult to obtain evidence for the transaction appeal

5) Data is easily retained by third-party trading platforms, which makes the platform a potential threat to the rights and interests of both parties in data transactions

6) The operation of the aerospace measurement and control network depends on the user orders sent by the trading platform, and the orders are often easily tampered with and forged during the transmission process, which poses a great threat to the safe and effective operation of the aerospace measurement and control network
