When Air Traffic Management Meets Blockchain Technology: a Blockchain-based concept for securing the sharing of Flight Data

Abstract

The Aviation industry has been booming for several decades and is expected to keep growing in the future. Therefore, Air Traffic Management (ATM) tools are likely to be soon overwhelmed by the demand. The Single European Sky ATM Research Program (SESAR) 2020, controlled by EUROCONTROL, intends to revisit the management of aeronautical information along its full lifecycle and across the whole European ATM system. The efficient sharing of information over large scale cyber physical systems is a non-trivial problem that raises several challenges including data lineage, data consistency, access rights management, and many more. Part of the SESAR initiative, System-Wide Information Management (SWIM) project defines standards to enhance the security of aeronautical data shared among stakeholders. Most of its propositions include centralized or partially centralized mechanisms in order to enforce data confidentiality, and privacy. In this paper, we intend to discuss how blockchains can improve the sharing of sensitive data over the ATM system. More specifically, we use the example of flight data and describe a highlevel Blockchain-based concept that mimics the decentralized nature of existing ATM system to provide a reliable, distributed storage platform for flight information.

BEAT-Traffic: a Blockchain-Enabled infrastructure for Anonymous-yet-Traceable Traffic reporting

“…Blockchain technology, popularized by Bitcoin in 2009 [4], has found its place in various industries besides DeFi, such as supply chain [9], space and aeronautics [10], [11], healthcare [12]. Thus, in addition, we propose to use a blockchain to develop a traffic reporting service that provides reliable, scalable, secure, and privacy-preserving data collection for DENMs in ITS.…”

An Ultra-Scalable Blockchain Platform for Universal Asset Tokenization: Design and Implementation

“…A great deal of future work is available in regard to prospective Alphabill partitions at various levels, i.e., in regard to business sectors, business domains and even single enterprises, as well as on cross-cutting aspects such a businessto-business communication [148], [149]. Various research studies have been conducted in regard to several business sectors such as e-health [150], energy [151], manufacturing [9], [11], [152], insurances [153], air traffic management [154], as well as public sector domains such as taxation, [155], e-procurement [156], [157] and land registration [158], just to name a few.…”

Enhancing IoT Data Security: Using the Blockchain to Boost Data Integrity and Privacy

“…Hyperledger Fabric is a private and permissioned blockchain that offers modularity, scalability, and a flexible permission model and is suitable for IoT deployments. Unlike public blockchains, permissioned blockchains such as Hyperledger Fabric restrict content publication to selected nodes, where access is controlled by a third party that manages user privileges [19,20]. This makes Hyperledger Fabric an ideal choice for meeting the specific security and privacy requirements of IoT applications.…”
