Our Achievements

Selection of HQC

Co-founders of PORTYQ contributed and lead the development and advancement of the HQC algorithm, which was selected by the NIST as a the second and last one post-quantum encryption standard. This achievement highlights our deep expertise in PQC and especially in code-based cryptography and our active role in shaping the next generation of quantum-resistant algorithms and their deployment.

First European Conference on the Quantum Threat

PORTYQ organized the first European conference entirely dedicated to quantum cybersecurity threat, bringing together leading experts from academia, industry and public institutions. This conference goal was to make people aware about the urgency of transitioning to quantum-safe solutions.
