CRYSTALS-Kyber
A lattice-based key encapsulation mechanism selected by NIST as the primary KEM in its post-quantum cryptography standards. It features moderate key sizes and fast computation, and its security has not been effectively broken under either classical or quantum computational models.
Timeline (last 90 days)
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.
CRYSTALS-Kyber (key encapsulation) and CRYSTALS-Dilithium (signatures), selected by NIST post-quantum standardization, are both built on the Module-LWE variant.
The n=256, q=3329 in the article are exactly the parameter scale used by Kyber, belonging to teaching-level simplified parameters; real Kyber's security parameters are larger and include engineering steps such as polynomial ring structure, compression, and NTT acceleration.
The post-quantum cryptographic algorithms already standardized by NIST include CRYSTALS-Kyber (key encapsulation) and CRYSTALS-Dilithium (digital signatures).
