- KEM combinerGlossary · A KEM combiner merges a classical and a post-quantum shared secret into one key that stays secure if either mechanism holds, the core of hybrid cryptography.
- Learning With Errors (LWE)Glossary · Learning With Errors (LWE) is the lattice problem of solving noisy linear equations, the hardness assumption underpinning most post-quantum encryption.
- Module Learning With Errors (Module-LWE)Glossary · Module-LWE is the structured lattice assumption behind ML-KEM and ML-DSA, tuning algebraic structure by module rank to reach each NIST security level.
- NIST security levelsGlossary · NIST security levels are five strength categories for post-quantum algorithms, each anchored to the cost of attacking AES or SHA-2 at a given size.
- NTRUGlossary · NTRU is the oldest practical lattice-based cryptosystem, a polynomial-ring public-key scheme from 1998 and the basis of the FN-DSA (Falcon) signature.
- Post-quantum cryptographyFoundations · Post-quantum cryptography is the field of cryptographic algorithms designed to resist attacks by both classical computers and future quantum computers.
- Ring Learning With Errors (Ring-LWE)Glossary · Ring-LWE is the polynomial-ring variant of Learning With Errors, trading extra algebraic structure for the compact keys and fast arithmetic PQ schemes need.
