Ronald J. Reisman, an aero-computer engineer at the Ames Research Center of NASA, has focused on a blockchain-based solution to tackle privacy problems and prevent such attacks as spoofing, DoS, etc.
He claims that a new platform is scheduled for introduction in 2020, it has been named the Automatic Dependent Surveillance-Broadcast. The system does not facilitate flight plans protection and positions, including other data. Reisman states that the blockchain can bring forth the solution via an engineering prototype created with help of a permissioned mainnet.
Utilization of an open source permissioned blockchain platform to allow the aircraft privacy and anonymity, also establishing a secure and effective means of communication with Operations Support, and Air Traffic Services, as well as other authorized entities.
The offered project will utilize certificate authority, support smart contracts, and communication channels at an increased bandwidth in order to ensure private communication between aircraft and authorized members.
He provides more details on the ways of economical and fast deployment of the prototype at scale, basing the offer on the utilization of Hyperledger Fabric, a blockchain he claims has been designed exclusively for enterprise use.
