Struct Aggregator 

pub struct Aggregator {
    pub num_keys: u32,
    pub threshold: u32,
    pub poly: Vec<Point>,
}

The group signature aggregator

Fields

num_keys: u32

The total number of keys

threshold: u32

The threshold of signing keys needed to construct a valid signature

poly: Vec<Point>

The aggregate group polynomial; poly[0] is the group public key

Implementations

impl Aggregator

pub fn sign_with_tweak( &mut self, msg: &[u8], nonces: &[PublicNonce], sig_shares: &[SignatureShare], _key_ids: &[u32], tweak: Option<Scalar>, ) -> Result<(Point, Signature), AggregatorError>

Aggregate the party signatures using a tweak. The posible values for tweak are None - standard FROST signature Some(0) - BIP-340 schnorr signature using 32-byte private key adjustments Some(t) - BIP-340 schnorr signature with BIP-341 tweaked keys, using 32-byte private key adjustments

pub fn check_signature_shares( &mut self, msg: &[u8], nonces: &[PublicNonce], sig_shares: &[SignatureShare], key_ids: &[u32], tweak: Option<Scalar>, ) -> AggregatorError

Check the party signatures after a failed group signature. The posible values for tweak are None - standard FROST signature Some(0) - BIP-340 schnorr signature using 32-byte private key adjustments Some(t) - BIP-340 schnorr signature with BIP-341 tweaked keys, using 32-byte private key adjustments

Trait Implementations

impl Aggregator for Aggregator

fn new(num_keys: u32, threshold: u32) -> Self

Construct an Aggregator with the passed parameters

fn init( &mut self, comms: &HashMap<u32, PolyCommitment>, ) -> Result<(), AggregatorError>

Initialize the Aggregator polynomial

fn sign( &mut self, msg: &[u8], nonces: &[PublicNonce], sig_shares: &[SignatureShare], key_ids: &[u32], ) -> Result<Signature, AggregatorError>

Check and aggregate the party signatures

fn sign_schnorr( &mut self, msg: &[u8], nonces: &[PublicNonce], sig_shares: &[SignatureShare], key_ids: &[u32], ) -> Result<SchnorrProof, AggregatorError>

Check and aggregate the party signatures

fn sign_taproot( &mut self, msg: &[u8], nonces: &[PublicNonce], sig_shares: &[SignatureShare], key_ids: &[u32], merkle_root: Option<[u8; 32]>, ) -> Result<SchnorrProof, AggregatorError>

Check and aggregate the party signatures

impl Clone for Aggregator

fn clone(&self) -> Aggregator

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Aggregator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Aggregator

fn eq(&self, other: &Aggregator) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
