[−][src]Struct frost_dalek::keygen::DistributedKeyGeneration
State machine structures for holding intermediate values during a distributed key generation protocol run, to prevent misuse.
Implementations
impl DistributedKeyGeneration<RoundOne>[src]
pub fn new(
parameters: &Parameters,
my_index: &u32,
my_coefficients: &Coefficients,
other_participants: &mut Vec<Participant>
) -> Result<Self, Vec<u32>>[src]
parameters: &Parameters,
my_index: &u32,
my_coefficients: &Coefficients,
other_participants: &mut Vec<Participant>
) -> Result<Self, Vec<u32>>
Check the zero-knowledge proofs of knowledge of secret keys of all the other participants.
Note
The participants will be sorted by their indices.
Returns
An updated state machine for the distributed key generation protocol if all of the zero-knowledge proofs verified successfully, otherwise a vector of participants whose zero-knowledge proofs were incorrect.
pub fn their_secret_shares(&self) -> Result<&Vec<SecretShare>, ()>[src]
Retrieve a secret share for each other participant, to be given to them
at the end of DistributedKeyGeneration::<RoundOne>.
pub fn to_round_two(
mut self: Self,
my_secret_shares: Vec<SecretShare>
) -> Result<DistributedKeyGeneration<RoundTwo>, ()>[src]
mut self: Self,
my_secret_shares: Vec<SecretShare>
) -> Result<DistributedKeyGeneration<RoundTwo>, ()>
Progress to round two of the DKG protocol once we have sent each share
from DistributedKeyGeneration::<RoundOne>.their_secret_shares() to its
respective other participant, and collected our shares from the other
participants in turn.
impl DistributedKeyGeneration<RoundTwo>[src]
pub fn finish(
mut self: Self,
my_commitment: &RistrettoPoint
) -> Result<(GroupKey, SecretKey), ()>[src]
mut self: Self,
my_commitment: &RistrettoPoint
) -> Result<(GroupKey, SecretKey), ()>
Calculate this threshold signing protocol participant's long-lived secret signing keyshare and the group's public verification key.
Example
let (group_key, secret_key) = state.finish(participant.public_key()?)?;
