In 2021, the National Security Research Institute (NSR) and the National Intelligence Service (NIS) established the Korean Post-Quantum Cryptography (KpqC) research group. To strengthen national post-quantum security against the rise of quantum computing, the KpqC competition for the Korean standard PQC scheme has begun. 

Since November 2022, the first round has been underway with 7 Key Encapsulation Mechanism (KEM) candidates and 9 Digital Signature candidates. In December 2023, 4 KEM algorithms and 4 Digital Signature algorithms have been advanced to the second round. The winners of the second round are expected to be chosen in November 2024.

In 2022, NIST chose three digital signature schemes to standardize: Dilithium, Falcon, and Sphincs+. NIST also announced that the PQC standardization process is continuing with a fourth round; however, no digital signature candidates are under consideration for the fourth standardization process. 

To continue the standardization, NIST posted a call for additional digital signature proposals, and in July 2023, Round 1 Additional Signatures were announced, including HAETAE. In October 2024, Round 2 candidates were announced, excluding all the MLWE/MSIS-based signatures.
