FIPS 203
A NIST post-quantum key encapsulation standard derived from the CRYSTALS-Kyber algorithm. It is intended to replace the key exchange functions of ECDH and RSA.
Timeline (last 90 days)
ML-KEM (formerly known as Kyber) is one of the first batch of post-quantum cryptographic algorithms formally standardized by NIST in the United States in 2024 (FIPS 203), constructed on the Learning With Errors problem over module lattices, and is immune to Shor's algorithm.
FIPS 203 (ML-KEM) is derived from CRYSTALS-Kyber and is used for key encapsulation, replacing the key exchange role currently played by ECDH and RSA.
