Crate frost_rerandomized 

FROST implementation supporting re-randomizable keys.

To sign with re-randomized FROST:

• Do Round 1 the same way as regular FROST;
• The Coordinator should call RandomizedParams::new_from_commitments() and send the generate randomizer seed (the second returned value) to all participants, using a confidential channel, along with the regular frost::SigningPackage;
• Each participant should regenerate the RandomizerParams by calling RandomizedParams::regenerate_from_seed_and_commitments(), which they should pass to sign_with_randomizer_seed() and send the resulting frost::round2::SignatureShare back to the Coordinator;
• The Coordinator should then call aggregate.

Structs

RandomizedParams

Randomized parameters for a signing instance of randomized FROST.

Randomizer

A randomizer. A random scalar which is used to randomize the key.

Traits

RandomizedCiphersuite

A Ciphersuite that supports rerandomization.

Functions

aggregate

Re-randomized FROST signature share aggregation with the given RandomizedParams.

aggregate_custom

Re-randomized FROST signature share aggregation with the given RandomizedParams using the given cheater detection strategy.

signDeprecated

Re-randomized FROST signing using the given randomizer, which should be sent from the Coordinator using a confidential channel.

sign_with_randomizer_seed

Re-randomized FROST signing using the given randomizer_seed, which should be sent from the Coordinator using a confidential channel.
