On July 17, 2023, the National Institute of Standards and Technology (NIST) announced a new set of 40 candidates to compete in their Post-Quantum Crypto Standardization Process for digital signatures. The call for these candidates was issued in September 2022 and ended June 1, 2023. This new round is independent of the ongoing standardization process of the CRYSTALS-Dilithium, FALCON and SPHINCS+ signature schemes that were chosen for standardization in July 2022.
