Post-Quantum Secure Communication and Surveillance for Air Traffic Management

Project description

Post-quantum security in air traffic management systems

The advancement of quantum computing will render existing cryptographic methods insufficient, making it imperative to develop solutions that are resistant to quantum attacks. In air traffic management (ATM), communication and surveillance systems may remain unauthenticated and insecure. The EU-funded PostQat project will enhance cybersecurity in ATM communication and surveillance systems by assessing needs across various segments and identifying urgent use cases for post-quantum cryptography (PQC). It will outline requirements for quantum-resistant security, design a public key infrastructure (PKI) tailored to aviation, and adapt NIST-standardised PQC algorithms for safety-critical environments. The project will provide blueprints and benchmarks, as well as assist in operationalising PQC in ATM. The goal is to secure data exchange in aviation.

Objective

PostQat addresses critical vulnerabilities in Air Traffic Management (ATM) communication and surveillance systems that remain unauthenticated and insecure, such as ADS-B, CPDLC, ACARS, and TCAS. The emergence of quantum computers will render current cryptography obsolete, creating an urgent need for quantum-resistant solutions.

The project’s objectives are to: (1) assess cybersecurity needs in European ATM across ground–ground, air–ground, and air–air segments; (2) identify high-impact operational use cases where post-quantum cryptography (PQC) is most urgent; (3) define detailed requirements for quantum-resistant security mechanisms; and (4) design a blueprint for a Public Key Infrastructure (PKI) and crypto-agility framework tailored to aviation.

These objectives will be achieved by surveying existing vulnerabilities, adapting NIST-standardised PQC algorithms to aviation’s safety-critical environment, and ensuring alignment with certification frameworks (DO-326A/ED-202A). PostQat will also leverage prior PQC research and provide open blueprints, benchmarks, and a practical roadmap for phased deployment.

The project directly contributes to HORIZON-SESAR-2025-DES-ER-03 by operationalising PQC in ATM, strengthening the cybersecurity foundations of the Digital European Sky, and enabling secure, trusted data exchange for both manned and unmanned aviation.
