Definition
The term, in context
AI-assisted draft · approved dataset
FIPS 203, 204, and 205 are the first finalized United States federal standards for post-quantum cryptography, specifying ML-KEM for key encapsulation and ML-DSA and SLH-DSA for digital signatures. The first two draw their security from the hardness of problems over module lattices, while SLH-DSA is stateless and hash-based, resting only on the properties of its underlying hash function so it remains a fallback if lattice assumptions weaken.
