Struct DkgSession 

pub struct DkgSession {
    pub authority_id: String,
    pub session_nonce: [u8; 32],
    pub ceremony_type: String,
}

A DKG session for forming (or re-sharing) an FTA.

Fields

authority_id: String

The authority being formed.

session_nonce: [u8; 32]

Session nonce — unique per ceremony.

ceremony_type: String

The ceremony type (dkg, reshare).

Implementations

impl DkgSession

pub fn pop_bytes(&self, member: &str, public_key: &[u8]) -> Vec<u8>

The bytes each member’s proof of possession signs.

pub fn verify_contributions( &self, pops: &[ProofOfPossession], quorum: Quorum, verifier: &dyn SignatureVerifier, ) -> SignatifResult<()>

Verify every contribution: each proof of possession checks out against its claimed key, and at least T of N members contributed. This is the rogue-key-attack prevention requirement.

Errors

Ceremony errors naming the first offending member.
