NIST ogłosił swoich pierwszych czterech finalistów:
NIST Announces First Four Quantum-Resistant Cryptographic Algorithms
Federal agency reveals the first group of winners from its six-year competition.
For general encryption, used when we access secure websites, NIST has selected the
CRYSTALS-Kyber algorithm. Among its advantages are comparatively small encryption keys that two parties can exchange easily, as well as its speed of operation.
For digital signatures, often used when we need to verify identities during a digital transaction or to sign a document remotely, NIST has selected the three algorithms
CRYSTALS-Dilithium, FALCON and SPHINCS+ (read as “Sphincs plus”). Reviewers noted the high efficiency of the first two, and NIST recommends CRYSTALS-Dilithium as the primary algorithm, with FALCON for applications that need smaller signatures than Dilithium can provide. The third, SPHINCS+, is somewhat larger and slower than the other two, but it is valuable as a backup for one chief reason: It is based on a different math approach than all three of NIST’s other selections.
Three of the selected algorithms are based on a family of math problems called structured lattices, while SPHINCS+ uses hash functions. The additional four algorithms still under consideration are designed for general encryption and do not use structured lattices or hash functions in their approaches.

Dla przypomnienia:
While no one knows exactly when quantum computers will be available, there is considerable urgency in moving to PQC as soon as possible. Many researchers say it's likely that criminals and nation-state spies are recording massive amounts of encrypted communications and stockpiling them for the day they can be decrypted.
