The National Cyber and Information Security Agency (NÚKIB) of the Czech Republic has declared its support for the message and content of the the “Position paper on Quantum Key Distribution”. NÚKIB agrees that, in the long term, it is desirable to continue research on quantum key distribution (QKD); however, the Agency also supports the main point made by the authors, namely that it is not feasible to rely on quantum-vulnerable public-key cryptography. The priority should instead be the transition to post-quantum cryptography (PQC) or the adoption of symmetric encryption.
“Position paper on Quantum Key Distribution” was published jointly in the beginning of 2024 by the French Cybersecurity Agency (ANSSI), the German Federal Office for Information Security (BSI), the Netherlands National Communications Security Agency (NLNCSA), and the Swedish National Communications Security Authority (Swedish Armed Forces).
As part of its activities, NÚKIB has been seeking to increase the resilience of communications against the threat posed by quantum computers. In this regard, the Agency has recently introduced quantum-resistant (post-quantum) cryptography to ensure the security of communication between a web browser and the NÚKIB Portal web application. Last year, the Agency also prepared supporting materials that explain the nature of the quantum threat and the steps that will need to be taken in the coming years to prevent it.
