Struct synedrion::KeyShare

pub struct KeyShare<P: SchemeParams> { /* private fields */ }

The full key share with auxiliary parameters.

Implementations

impl<P: SchemeParams> KeyShare<P>

pub fn new_centralized( rng: &mut impl CryptoRngCore, num_parties: usize, signing_key: Option<&SigningKey> ) -> Box<[Self]>

Returns num_parties of random self-consistent key shares (which in a decentralized case would be the output of KeyGen + Auxiliary protocols).

pub fn update(self, change: KeyShareChange<P>) -> Self

Return the updated key share using the share change obtained from the KeyRefresh+Auxiliary protocol).

pub fn verifying_key(&self) -> VerifyingKey

Return the verifying key to which this set of shares corresponds.

pub fn num_parties(&self) -> usize

Returns the number of parties in this set of shares.

pub fn party_index(&self) -> usize

Returns the index of this share’s party.
