//! # smart-byte-pq
|
|
//!
|
|
//! Post-quantum signature algorithms for the Smart Byte substrate.
|
|
//!
|
|
//! NIST finalised the first three post-quantum signature standards in
|
|
//! August 2024:
|
|
//!
|
|
//! * **FIPS 204 — ML-DSA** (Module-Lattice-Based Digital Signature
|
|
//! Algorithm, formerly CRYSTALS-Dilithium). Three parameter sets:
|
|
//! ML-DSA-44, ML-DSA-65, ML-DSA-87.
|
|
//! * **FIPS 205 — SLH-DSA** (Stateless Hash-Based Digital Signature
|
|
//! Algorithm, formerly SPHINCS+). Twelve parameter sets across two
|
|
//! hash families (SHA-2, SHAKE), three security levels (128, 192,
|
|
//! 256 bit), and two size/speed trade-offs (small `s`, fast `f`).
|
|
//! * **Draft FIPS 206 — FN-DSA** (FFT-over-NTRU Digital Signature
|
|
//! Algorithm, formerly Falcon). Two parameter sets: FN-DSA-512 and
|
|
//! FN-DSA-1024. The FIPS 206 standard is in late draft as of mid-2025;
|
|
//! for that reason the FN-DSA implementation in this crate is gated
|
|
//! behind the `falcon` feature. When the feature is off, the public
|
|
//! API is preserved (so callers can still match on the enum variants)
|
|
//! but the signer functions return [`error::PqError::UnsupportedAlgorithm`].
|
|
//!
|
|
//! Smart Byte signs *envelope SAIDs* (BLAKE3 commitments to the
|
|
//! canonical CBOR encoding of an envelope with `id` zeroed). The choice
|
|
//! of signature algorithm is selected per envelope via the one-byte
|
|
//! *algorithm identifier* defined in the Smart Byte spec
|
|
//! (`§4.1 / §8.3 / §8.4 / §19`). This crate provides the wire-side
|
|
//! signer/verifier implementations for every algorithm in the enum.
|
|
//!
|
|
//! The default for v1 envelopes remains Ed25519; PQ algorithms are
|
|
//! opt-in per envelope until the substrate-wide migration cutover
|
|
//! described in `§19.5` / `§19.8`.
|
|
//!
|
|
//! ## Hybrid signatures
|
|
//!
|
|
//! For the transition period NIST and the IETF
|
|
//! (`draft-ietf-pquip-pqt-hybrid-terminology`) recommend hybrid
|
|
//! signatures that combine a classical scheme (Ed25519 or ECDSA-P256)
|
|
//! with a post-quantum scheme (typically ML-DSA). A hybrid signature
|
|
//! is valid only if **both** component signatures verify; an attacker
|
|
//! must break both schemes to forge one. See [`hybrid`].
