National Aeronautics and Space Administration, NASA published a proposal on January 10, which talks about the idea of using the air traffic management blockchain. For this purpose, the blockchain technology developed by Hyperledger Fabric was judged to be the most suitable.
The document entitled "Air Traffic Management Blockchain Infrastructure for Security, Authentication and Privacy" states that the current air traffic management system maintains its privacy and security "procedurally preventing public release of flight plans, location and data been selected ". the imminent national adoption by the United States of the automatic transmission system of employee monitoring (ADS-B) by 2020, although it may be better, but the integration of the same security measures may not be exactly possible ; moreover, ADS does not adhere to the "potential for spoofing, denial of service and other well-documented risk factors", leaving it bare when it comes to high-level privacy and security.
Unfortunately, many other articles have been presented to interested parties suggesting solutions to this problem, but all have been rejected. Now NASA is examining the potential of blockchain technology to solve the problem. Specifically, the card presents "certification authorities, support for smart contracts and communication channels with higher bandwidth for private information that can be used for secure communications between any
aircraft and any other authorized member, sharing data in accordance with the specified terms in the form of smart contracts. "
The blockchain will be used to optimize the ADS security system via a PKI blockchain for aeronautical surveillance applications. The document states that Hyperledger Fabric is the most suitable for the purpose. According to the document, Hyperledger is a distinct form of other token-based blockchains. It has some features such as the provision of "private channels" that allow private communications at a higher bandwidth. Likewise, the functionality of smart contracts works well for the privacy and security of ADS. The document states:
These private channels can be used to pass a private key (or a time-key data structure) suitable for encrypting ADS-B Out transmissions between any specific aircraft and any authorized member in accordance with the terms of the smart contracts associated with the particular private channel (and subnet). The use of cyphertext allows ADS-B users to maintain privacy and anonymity from the general public while providing a secure and efficient method for communicating with authorized entities, such as air traffic services or air operations services. "
Even NASA's attempts to promote research and the use of blockchain have been seen before. NASA has been at stake since 2017 when it awarded a $ 330,000 grant that supported the development of an autonomous blockchain space vehicle system.
