Beyond the Limits of Post-quantum cryptography

The BlimPQC - Beyond the Limits of Post-Quantum Cryptography project investigates the possibilities and limitations of new Post-Quantum Cryptography methods and the requirements for different devices and software where encryption is used. In the long term, quantum computing and quantum computers pose a significant threat to the currently widely used public key encryption methods. These threats can be mitigated with post-quantum cryptography, and due to recent developments, the standardization of new methods has progressed rapidly and will be available as early as 2024. This project explores the use and limitations of these new encryption algorithms that will be standardized, and studies the possibilities of quantum computing in breaking encryption methods. In addition to encryption algorithms, we investigate the use of quantum key exchange and key management. New methods are implemented in the use cases of different companies. We also make a review of quantum security regulation and requirements abroad, especially in the United States, where the first related law was set already in December 2022. During the project, high-level guidelines are created and published for relevant stakeholders based on the findings of research and experiments.
