Struct frost_rerandomized::RandomizedParams

pub struct RandomizedParams<C: Ciphersuite> { /* private fields */ }

Randomized params for a signing instance of randomized FROST.

Implementations

impl<C> RandomizedParams<C>where C: Ciphersuite,

pub fn new<R: RngCore + CryptoRng>( public_key_package: &PublicKeyPackage<C>, rng: R ) -> Self

Create a new RandomizedParams for the given PublicKeyPackage

pub fn randomizer(&self) -> &Scalar<C>

Return the randomizer.

It can be useful to the coordinator, e.g. to generate the ZK proof in Zcash. It MUST NOT be sent to other parties.

pub fn randomizer_point(&self) -> &<C::Group as Group>::Element

Return the randomizer point.

It must be sent by the coordinator to each participant when signing.

pub fn randomized_group_public_key(&self) -> &VerifyingKey<C>

Return the randomized group public key.

It can be used to verify the final signature.
