ML-KEM: Module Lattice Key Encapsulation
The NIST-standardized post-quantum key exchange algorithm (formerly Kyber).
🛡️ NIST Standardized (FIPS 203)
ML-KEM is the primary NIST post-quantum key encapsulation standard, published August 2024. It replaces RSA and ECDH key exchange for quantum-resistant applications.
📖 Definition
ML-KEM (Module Lattice-Based Key Encapsulation Mechanism) is the NIST-standardized name for Kyber, published as FIPS 203. It enables two parties to establish a shared secret key resistant to quantum computer attacks, serving as the foundation for quantum-safe encrypted communications.
Technical Explanation
ML-KEM operates through three core functions that enable secure key establishment:
- KeyGen(): Generates a public-private key pair using lattice operations
- Encapsulate(pk): Uses the public key to create a ciphertext and shared secret
- Decapsulate(sk, ct): Uses the private key to recover the shared secret from ciphertext
Security Foundation
ML-KEM security derives from the Module Learning With Errors (MLWE) problem—a mathematical challenge believed intractable for both classical and quantum computers. No efficient quantum algorithm is known to solve MLWE.
Parameter Sets
| Parameter Set | NIST Security Level | Public Key Size | Ciphertext Size |
|---|---|---|---|
| ML-KEM-512 | Level 1 (~128-bit) | 800 bytes | 768 bytes |
| ML-KEM-768 | Level 3 (~192-bit) | 1,184 bytes | 1,088 bytes |
| ML-KEM-1024 | Level 5 (~256-bit) | 1,568 bytes | 1,568 bytes |
ML-KEM vs Kyber: What Changed?
During NIST standardization, minor adjustments were made to the original Kyber specification:
- Name change: Kyber → ML-KEM (Module Lattice-Based KEM)
- Parameter naming: Kyber-768 → ML-KEM-768
- Minor spec adjustments: Encoding and test vector refinements
- Core algorithm: Mathematically identical security properties
