Traits

Ciphersuite

A FROST ciphersuite specifies the underlying prime-order group details and cryptographic hash function.

Field

A prime order finite field GF(q) over which all scalar values for our prime order group can be multiplied are defined.

Group

A prime-order group (or subgroup) that provides everything we need to create and verify Schnorr signatures.

Functions

aggregate

Verifies each FROST(Decaf377, BLAKE2b-512) participant’s signature share, and if all are valid, aggregates the shares into a signature to publish.

Type Aliases

Error

An error type for the FROST(Decaf377, BLAKE2b-512) ciphersuite.

Identifier

A FROST(Decaf377, BLAKE2b-512) participant identifier.

RandomizedParams

Randomized parameters for a signing instance of randomized FROST.

Signature

A Schnorr signature on FROST(Decaf377, BLAKE2b-512).

SigningKey

A signing key for a Schnorr signature on FROST(Decaf377, BLAKE2b-512).

SigningPackage

Generated by the coordinator of the signing operation and distributed to each signing party.

VerifyingKey

A valid verifying key for Schnorr signatures on FROST(Decaf377, BLAKE2b-512).
