The US National Aeronautics and Space Administration (NASA) has proposed a blockchain for air traffic management, according to an article published on the official website of the agency on January 10th.
The proposed system would employ an authorized open source blockchain to allow secure, private and anonymous communications with air traffic services. The document notes:
"This framework includes a certification authority, support for smart contracts and broadband bandwidth communication channels for private information that can be used for secure communications between any specific aircraft and any specific authorized member."
The engineering prototype of the system used the Hyperledger fabric and demonstrated that this infrastructure could be quickly implemented and maintained economically.
In December of last year, Hyperledger – an open source project created by the Linux Foundation and created to support the development of blockchain-based distributed master books – has assembled 12 new members, including major companies such as Alibaba Cloud, Citi and Deutsche Telekom.
According to the document, the automatic employee monitoring system (ADS-B) – which will be mandatory by 2020 – is subject to third party spoofing as it publicly transmits aircraft positions. Spoofing, the researchers explain, is when the false position of the aircraft is reported.
The researchers note that the implementation of cryptography has been proposed to address both privacy and spoofing issues. Furthermore, the proposal explains the difficulties of these solutions:
"An exceptional problem in most of these PKIs [Public Key Infrastructure] regimes is the difficulty of implementing the public reference framework so that it can be used by aircraft in flight ".
According to the proposal, corporate blockchain solutions could be a practical PKI for aeronautical applications. The document states:
"A virtue of these blockchain schemes is that they allow the implementation of a PKI infrastructure in which end users are not required to belong to any single organization, or to adhere to any single client / server protocol. "
In the prototype, the Fabric Certificate Authority is used for the registration of the entities, the issue, the renewal and the revocation of the enrollment certificates. A system like this, according to the newspaper, "would allow ADS-B systems to meet or exceed the same level of privacy and security currently provided by radar systems in the NAS."
As Cointelegraph reported in an analysis dedicated to space blockchain in August 2018, NASA awarded a $ 330,000 grant in 2017 that supported the development of an autonomous, blockchain-based spacecraft system that moved the first move towards the adoption of blockchain.
Moreover, in December last year, the news broke Blockstream, a blockchain development company, which has expanded its satellite service with the fifth satellite and is transmitting the Bitcoin blockchain (BTC) to all the main land masses. of the Earth.
