And then there were four: the first NIST PQC standards

Abstract: In July 2022, NIST selected four public-key quantum-resistant algorithms for standardization after a lengthy evaluation period: Crystals-Kyber, Crystals-Dilithium, Falcon, and SPHINCS+.  Last month the draft versions of the standards were posted for public comment, with the goal of having the first post-quantum cryptographic (PQC) standards finalized and published in 2024.  In this talk, I will give a quick summary of the PQC project, and then briefly discuss how the four selected algorithms work from a high level.  It may be interesting to explore if threshold-friendly implementations of these algorithms are possible.
