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() and send the RandomizedParams::randomizer to all participants, using a confidential channel, along with the regular frost::SigningPackage;
• Each participant should call sign and send the resulting frost::round2::SignatureShare back to the Coordinator;
• The Coordinator should then call aggregate.

Re-exports

• pub use frost_core;

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, which can be computed from the previously generated randomizer using RandomizedParams::from_randomizer.
• sign
  Re-randomized FROST signing using the given randomizer, which should be sent from the Coordinator using a confidential channel.
