Methods

impl PedersenDVSSParticipant

pub fn new(id: usize, threshold: usize, total: usize, g: &G1, h: &G1) -> Self

Generates a new secret and verifiable shares of that secret for every participant

pub fn received_share(
    &mut self,
    sender_id: usize,
    comm_coeffs: HashMap<usize, G1>,
    share: (FieldElement, FieldElement),
    threshold: usize,
    total: usize,
    g: &G1,
    h: &G1
)

Called by a participant when it receives a share from another participant with id sender_id

pub fn compute_final_comm_coeffs_and_shares(
    &mut self,
    threshold: usize,
    total: usize,
    g: &G1,
    h: &G1
)

Called by a participant when it has received shares from all participants. Computes the final share of the distributed secret
