sign: Add MLD_CONFIG_MAX_SIGNING_ATTEMPTS and dedicated error code by hanno-becker · Pull Request #1059 · pq-code-package/mldsa-native

hanno-becker · 2026-04-24T09:04:40Z

Introduce a new configuration option, MLD_CONFIG_MAX_SIGNING_ATTEMPTS, that bounds the number of rejection-sampling iterations performed by the ML-DSA signing routine (FIPS 204, Algorithm 7). This is useful in timing-sensitive environments that require a deterministic worst-case bound on signing time.

The default is the maximum value before non-overflow -- practically infinite. A compile-time check rejects values below the FIPS 204 Appendix C minimum of 814 (at which exhaustion has probability < 2^-256).

When the bound is reached, signing now returns a dedicated error code MLD_ERR_SIGN_ATTEMPTS_EXHAUSTED instead of the generic MLD_ERR_FAIL. CBMC specifications and documentation for all signing entry points are adjusted accordingly. The PCT path (mld_check_pct) and keypair contracts are also updated because the new code can propagate through MLD_CONFIG_KEYGEN_PCT.
