Struct frost_schnorrkel::frost::dkg::pedpop::KeyMachine

pub struct KeyMachine<C>
where
    C: Ciphersuite,
{ /* private fields */ }
Available on crate feature std only.
Expand description

Advancement of the the secret share state machine.

This machine will ‘complete’ the protocol, by a local perspective. In order to be secure, the parties must confirm having successfully completed the protocol (an effort out of scope to this library), yet this is modeled by one more state transition (BlameMachine).

Implementations§

source§

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

source

pub fn calculate_share<R>( self, rng: &mut R, shares: HashMap<Participant, EncryptedMessage<C, SecretShare<<C as Ciphersuite>::F>>>, ) -> Result<BlameMachine<C>, DkgError<EncryptionKeyProof<C>>>
where R: RngCore + CryptoRng,

Calculate our share given the shares sent to us.

Returns a BlameMachine usable to determine if faults in the protocol occurred.

This will error on, and return a blame proof for, the first-observed case of faulty behavior.
