Korean Post-Quantum Cryptography Competition

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. 

NIST Post-Quantum Cryptography: Digital Signature Schemes

In 2022, NIST has chosen 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, there are no digital signature candidates under consideration to continue 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.
