Austria is a pioneer in quantum cryptography for the protection of critical infrastructure data
Austria has taken a significant step in the research and application of quantum technology as an encryption technology for critical infrastructures. The use case tested by CANCOM Austria in January 2024 has shown that cryptographic data keys based on quantum entanglement can be successfully exchanged between two data centers. This technology offers a high level of security against conventional cyber attacks as well as attacks using quantum computers. The project, which is scheduled to run for 18 months and is led by the Austrian Institute of Technology (AIT) and involves besides CANCOM Austria, the Austrian Research Promotion Agency (FFG) and the Federal Ministry of Defense (BMLV), is particularly important for securing data traffic in critical infrastructures.
Quantum technologies make everyday life safer and protect against future security threats
Quantum technologies are revolutionizing communication by using new, secure encryption options that make messages almost completely tap-proof. This is because there is a risk that (quantum) computers could be used to crack data encryption in the future, for example in financial transactions.
This is where quantum cryptography in the form of QKD (Quantum Key Distribution) comes into play again. QKD is a method for the secure transmission of encryption keys that is based on the laws of quantum physics. By using individual particles of light (photons), any unauthorized eavesdropping is automatically detected and the key is rendered unusable, enabling absolutely secure communication.
Network and security expertise from CANCOM Austria
In the CANCOM Austria research laboratory, the experts worked intensively with their partners on the development of the new technology and, with the developed source code "Arnika" as an open source extension of WireGuard* VPN, enabled quantum-resistant VPN connections that offer new possibilities for tap-proof transmission of data, especially for critical infrastructure and security-relevant sectors such as public administration, military facilities and the financial and energy sectors.
"Arnika" uses cryptographic keys generated by a quantum key distribution (QKD) system based on quantum mechanical principles. These keys are used in a VPN connection with WireGuard* and are used for symmetric encryption of various applications. In addition, hybrid encryption can be created with a combination of QKD and post-quantum cryptography (PQC) systems, which ensures reliability in the event of attacks on one of the systems.
"As a driver of innovation, we are taking on a clear pioneering role in this project together with our partners and are thus also making an important contribution to data security and data sovereignty in Austria and Europe. We are currently planning further proofs of concept with our customers from the critical infrastructure sector," says Andreas Neuhold, Senior Manager Security at CANCOM Austria.
