Implementations§

impl MPCProver

Source

fn generate_secure_shamir_secret_share_slopes_and_commitments<C: PrimeOrderCurve>( num_vars: usize, log_num_cols: usize, pedersen_committer: &PedersenCommitter<C>, rng: &mut impl Rng, ) -> HyraxProverInputCommitment<C>

Computes a set of random Shamir secret share slopes and creates a Hyrax commitment for them.

Note that rng should be a CSPRNG seeded with a strong source of device entropy! Recommended to call this with OsRng and ChaCha20Rng.
