Blockchain-Based Trust Model for Air Traffic Management Network

Abstract

The Air Traffic Management (ATM) system is a network-centric intelligent information system that faces severe and complex challenges in the process of aviation information interaction. From the perspective of data security transmission in ATM networks, this paper proposes a blockchain-based trust model BlockTrust, combined with domestic cryptographic algorithms to establish a trust chain in the ATM air-space-ground integrated network. This paper uses such distributed ledger technology to design an architecture for ensuring the security of ATM information, ensuring the secure transmission and reliable sharing of aviation business data. In this paper, we will also take the submission and update process of flight plans as an example to discuss the possible benefits and risks of applying blockchain in this field.
