Module-Lattice-Based Digital Signature Algorithm
ML-DSA, standardized by NIST as FIPS 204 in 2024, is the primary post-quantum digital signature algorithm, derived from the CRYSTALS-Dilithium submission. Its security is based on lattice problems believed to resist attacks by both classical and quantum computers. It is the general-purpose signature counterpart to ML-KEM and is being adopted in certificates, code signing, and protocol suites as organizations migrate away from RSA and ECDSA.
