In December 2016, NIST began a program to select the best PQC algorithms in the area of public key cryptography. In July 2022, after several rounds of the competition, NIST announced the first set of algorithms to be standardized for digital signature and key establishment methods. The resulting standardization process is expected to take approximately 2 years.

NIST has selected four PQC algorithms from round 3 of its competition for standardization. For key establishment method, the algorithm that NIST has selected is CRYSTALS-KYBER. For digital signatures, NIST has selected three algorithms: CRYSTALS-DILITHIUM, FALCON, and SPHINCS+.

Further details will be added later.
