The U.S. National Aeronautics and Space Administration (NASA) is exploring blockchain capabilities for the secure and confidential storage of flight data. The proposal was made by an engineer from NASA research centers Ronald Reisman (Ronald Reisman).
Engineer Reisman recently published his own study, which explained how the chain of blocks could solve current problems and prevent vulnerabilities in the future. As of January 1, 2020, the Automatic Broadcast Dependent Surveillance System (AZN-B) will begin operating in the United States, ensuring better aircraft traceability.
Because data on vessel status and weather conditions, as well as course, altitude, speed and other aircraft parameters are publicly transmitted, the system has been criticized. As Reisman noted, AZN-B “does not provide the same capabilities to ensure aircraft security and does not protect against phishing attacks, denial of service and other known risks.
He added that civil aviation companies would prefer to hide some data to avoid industrial espionage. In addition, according to the engineer, the U.S. Department of Defense is likely to refuse to switch to a new system because of the strategic importance of information about military aircraft.
As conceived by Reisman, integration with a distributed registry neutralizes data from AZN-B defects. The prototype aviation block chain infrastructure (ABI) presented by him is a “semi-private block chain” and allows him to use all the advantages of AZN-B while hiding confidential information.
For example, information about the status of the ship (speed, altitude, current course) can be sent through closed channels, while general information about the route, flight duration and aircraft type will be transmitted openly.
The prototype, believed to be Reisman, “will allow AZN-B to match or even exceed the confidentiality and security standards of the national airspace system radar networks.
The fact that NASA plans to integrate the blockchain with aerospace navigation and surveillance systems became known in February 2018, when the agency published a presentation on the applied perspectives of the technology. Later, in April, NASA became one of the sponsors of the project to build an autonomous spacecraft using the Ethereum network.
