The United States NASA or National Aeronautic and Space Administration, has some plans to advance its technology, as it proposed an air traffic management blockchain, to secure air traffic services, as well as support. In order to achieve this purpose, the space agency is going to work with HiperLedger Fabric Certificate Authority. The news came from a white paper which was published on the official website of the agency on the 10th of January.

Enabling secure, private an anonymous communication with air traffic services

The proposed system of NASA is going to employ an open-source-approved blockchain to enable secure, as well as private and anonymous communication with air traffic services.

The document noted that the framework features certificate authority, smart contract support, as well as higher-bandwidth communication channels for private information which may be utilized for secure communication between any specific aircraft and a particular authorized member.

The entire arrangement is centered on blockchain technology which is different from Bitcoin blockchain, privately set to utilize separate ledgers in collecting data.

It is also going to enable control over the data shared publicly or also privately by authorized entities, sharing data following the terms specified in the form of smart contracts. The prototype also demonstrates how the method may be economically and rapidly deployed in a scalable, modular environment.

Implementing cryptography to address spoofing and privacy

In December 2017, HyperLedger, which is an open source project that is created by the Linux Foundation and designed to support the development of blockchain-based distributed ledgers – onboard 12 new members, including some notable firms such as Alibaba Cloud, Citi, and Deutsche Telekom.

According to the same white paper, the Automatic Dependent Surveillance System or ADSB, which is going to be mandatory by 2020, is subject to third-party spoofing as it publicly broadcasts aircraft positions. Spoofing, according to the explanations of the researchers, is when false aircraft position is reported.

The researchers also noted that implementing cryptography was proposed to address both the privacy and spoofing. Moreover, the proposal explains the difficulties of such solutions, saying that an outstanding issue in most of the PKI or Public Key Infrastructure schemes is the difficulty of implementing the public key framework in a manner which may be applied by aircraft in flight.

According to the scheme, enterprise blockchain answers could actually be a practical PKI for aircraft applications. The document stated that virtue of theses blockchain schemes is that which they authorize implementation of a PKI infrastructure, what means that users are actually not required to belong to any single organization or also adhere 6 to any individual client or server protocol.

NASA involved in moves to support blockchain technology

In the prototype model, the Fabric Certificate Authority is actually employed for the registration of issuance, revocation, entities, and renewal of Enrollment Certificates. According to the white paper, such as system is going to enable ADCB systems to meet or exceed the same level of privacy, as well as currently provided by radar-based systems in the space agency.

NASA is a government body which is in charge of civilian space programs, as well as aeronautics and space research. Its adoption of blockchain technology is just part of the US government proposal to secure data involving military, as well as corporate activities via blockchain.

NASA was also involved in moves to support blockchain projects, and it supported a professor at Akron University with $330,000 in 2017 to promote a research on how an Ethereum based blockchain technology may automatically dictate floating debris, and it also supported the development of an autonomous, blockchain0based spacecraft system, making its first move toward blockchain adoption.

Moreover, in December 2018, news broke that Blockstream, which is a blockchain development firm, has expanded its satellite service with the fifth satellite and is now broadcasting the Bitcoin or BTC blockchain to all of the major land masses on Earth.
