PostQuantum.SecretSharing.Vss

Opt-in Verifiable Secret Sharing (VSS) for PostQuantum.SecretSharing. Detect a malicious dealer who hands inconsistent shares to different trustees, so every quorum is guaranteed to reconstruct the same secret.

Preview, unaudited new cryptography. Ships as 2.0.0-preview. See the honest tradeoff below and docs/VSS-DESIGN.md in the repository.

Why this is a separate package

The core PostQuantum.SecretSharing library is dependency-free and its secrecy is information-theoretic / post-quantum. VSS needs a prime-order group (NIST P-256 via a vetted EC dependency), so it lives here — you opt in to that dependency and to one specific tradeoff:

  • Secrecy stays unconditional. Pedersen commitments are perfectly hiding: the commitment transcript reveals nothing about the secret, against any adversary, including a quantum one. The headline guarantee is untouched.
  • Malicious-dealer detection is computational. Commitment binding rests on discrete-log hardness. A quantum dealer could defeat the consistency check — not the secrecy. We document this exactly the way the core documents its ML-DSA layer.

Status

Design-complete; implementation in progress. The public API and .pqss v2 wire format are specified in docs/VSS-DESIGN.md and will be pinned with test vectors before the preview is published.
