A definitive engineering guide comparing performance, memory footprints, signature sizes, and security guarantees between NIST's primary digital signature standards.
A comprehensive side-by-side comparison of FIPS 204 (ML-DSA, based on Module-LWE/SIS) and FIPS 205 (SLH-DSA, based on Merkle hypertrees). While ML-DSA offers small signatures (2.4 KB) and lightning-fast verification, SLH-DSA offers unmatched mathematical longevity and minimal public key sizes (32 bytes).
Guidelines for enterprise architects on where to deploy each algorithm: ML-DSA for TLS handshakes, user authentication, and high-frequency API signing; SLH-DSA for root Certificate Authorities, code signing, operating system kernels, and long-term legal archival.
Detailed architectural blueprints for generating dual-signature certificates and software packages, combining the speed of ML-DSA with the unbreakable longevity of SLH-DSA.
