Post-Quantum Cryptography (PQC)

We are securing communication and data against future quantum attacks.

Post-Quantum Cryptography (PQC) is a type of cryptographic defense that aims to protect against the immense computing power of quantum computers. It provides a proactive approach to security, safeguarding sensitive data against the future threat of quantum computing in various critical and emerging technologies. Advances in quantum computing could make today’s encryption methods easy to crack, thereby exposing data that was once believed to be secure for an extended period in a matter of moments. Moreover, digital certificates and signatures serve as the basis of trust in our digital transactions, and future authentication mechanisms could also be compromised, potentially undermining the foundation of online identity and trustworthiness. Therefore, we see PQC as a crucial component in several domains, including IoT, telecommunication, large and potentially system-critical infrastructures, financial services, healthcare, government and defense, and transportation.

In contrast to Quantum Key Distribution (QKD), which requires a significant shift in communication protocols and specialized equipment, PQC is an extension of well-tested and understood Public Key Infrastructure (PKI) systems, allowing it to be seamlessly integrated into today’s computing infrastructure with minimal disruption.

End-to-End Quantum Safe Security for Satellite Data Links (E2EQSS)

Press Release, 22.03.2024

European Space Agency Supports Quantum-Safe Satellite Data Link Project

In the framework of the ARTES strategic programme line Space Systems for Safety and Security (4S), the European Space Agency (ESA) awarded a contract for the innovative End-to-End Quantum-Safe Security for Satellite Data Links (E2EQSS) project to shield satellite communications from emergent quantum threats. This pioneering initiative will revolutionize the commercial space industry by implementing an all-encompassing quantum-safe security framework, safeguarding satellite data communications against future cryptographic vulnerabilities.

The E2EQSS project is a pioneering effort designed to incorporate asymmetric quantum-safe cryptography, also known as post-quantum cryptography, to facilitate quantum-safe key distribution tailored explicitly for future satellite constellations. By seamlessly integrating space and ground components, the project aims to establish a fortified barrier against the advances of quantum computing threats.

At the helm of this ambitious project is a consortium of four leading partners, each renowned for their distinct expertise and contributions to secure communications. VisionSpace Technologies GmbH, with its profound knowledge of ground components, is set to ensure the seamless operation and security of the project’s terrestrial infrastructure. Complementing this, ID Quantique SA, the global leader in Quantum Cybersecurity, brings its state-of-the-art quantum random number generator chips, a critical component for the encryption and protection of data transmissions. Certified to ECSS-Q-ST-60-13, IDQ’s Chips serve the entire range of mission profiles for use in space requiring Rad Hard or Rad Tolerant devices. ATELERIS GmbH contributes its specialized skills in satellite onboard software, optimizing the performance and security of satellite operations. FHNW HT-ISE, a leading research institution, rounds up the consortium and provides extensive knowledge in quantum-safe security, steering the project’s scientific and technological trajectory.

Together, these partners are committed to developing a robust, quantum-safe ecosystem for satellite data links. This collaborative effort marks a significant step forward in the quest for secure space communications, paving the way for a new industry standard in the face of evolving quantum challenges. As the E2EQSS project progresses, its developments are poised to revolutionize the way we approach security in space communications, ensuring that our global networks remain secure and resilient in the quantum era.
