AROBS Poland will develop a satellite communication security system for ESA based on post-quantum algorithms

AROBS Poland has been selected by the European Space Agency to develop and implement the Post-Quantum Cryptography Algorithms for Satellite Telecommunication Applications (PQC ASTrAL) project. The aim of the project is to develop a cryptography system for satellites based on post-quantum algorithms, which will ensure that communications are protected from the new threats posed by quantum computers.

The development of quantum computing poses significant challenges for cybersecurity, with the potential risk of compromising traditional cryptographic algorithms. To counter this risk, the PQC ASTrAL project aims to implement a cryptographic system that is resistant to quantum attacks, enabling satellites to perform authentication, digital signatures and encryption in a secure and sustainable manner in the long term. The initiative is part of the Advanced Research in Telecommunications Systems (ARTES) Space Systems for Safety and Security (4S) programme in the European Space Agency’s Directorate of Communications and Secure Communications.

The company is the prime contractor responsible for developing the hardware and firmware hosting the cryptographic IP core, as well as the associated software. ResQuant, a company specialising in cryptographic solutions implemented in hardware, is a subcontractor responsible for the cryptographic aspects of the project.

“We are very pleased that AROBS Poland has been selected for another ESA project. The rapid development of quantum computers poses a major challenge to cybersecurity, as traditional encryption systems become vulnerable to the extraordinary computing power of future quantum computers. Compromised cryptographic keys can have serious consequences, ranging from the unauthorised interception of communications to the hijacking of devices. In this context, the solution developed by AROBS Poland as part of the PQC ASTrAL project is an essential response to a real threat and will contribute to the long-term security of satellite communications,” said Voicu Oprean, founder and CEO of AROBS.

The system developed by the Polish company will enable the generation and management of cryptographic keys both on satellites and at mission control stations, data encryption and authentication, as well as key verification using post-quantum methods standardised by the US National Institute of Standards and Technology in August 2024. It will also enable the distribution and validation of software packages for satellites. The solution has been designed to meet international security standards and will be compatible with SpaceWire and SpaceFibre, two high-speed airborne communication protocols that facilitate data transfer between systems on board a satellite and other spacecraft.

“Securing satellite communications is a complex challenge, especially for long-lived assets with limited physical access. Updating software, cryptographic certificates and key negotiation mechanisms are key processes for maintaining security, but weaknesses in current systems can allow attacks using forged digital signatures or compromised cryptographic keys. With the rapid development of quantum computers, traditional cryptographic standards no longer provide long-term security guarantees,” said Michal Szwajewski, CEO of AROBS Poland. – By integrating post-quantum algorithms and implementing security mechanisms in hardware, the PQC ASTrAL project significantly reduces these risks by separating cryptographic processing from the satellite’s core systems and minimising vulnerability to cyber-attacks. This approach provides a high level of security for satellite communications and anticipates industry needs many years ahead. – he adds.

National security agencies in Europe are urging the transition of critical infrastructure to post-quantum cryptography. ESA is very pleased to work with AROBS Poland to develop a quantum-safe cryptographic system to secure the satellite communications infrastructure against new threats, enabling Europe to safely exploit advances in quantum computing and defend against related attacks,’ concludes Laurent Jaffart, ESA’s Director of Communications and Secure Communications.
