Quantum Minute. Post-Quantum Encryption: NIST Picks HQC. Sponsored by Applied Quantum.

The U.S. National Institute of Standards and Technology (NIST) has selected the Hamming Quasi-Cyclic (HQC) algorithm as a backup post-quantum encryption standard, adding a fifth quantum-resistant tool to its lineup of post quantum cryptography (PQC) standards. Unlike the primary standard ML-KEM – which is based on a complex type of multi-dimensional modelling called lattice mathematics – HQC uses code-based cryptography, offering an alternative defense in case future quantum breakthroughs threaten the integrity of lattice-based systems. HQC emerged from NIST’s fourth round of evaluation, where it outperformed similar candidates like BIKE and Classic McEliece due to its strong security and practical performance.
