Add Ed25519 to FROST and remove expand_xmd for elliptic_curve's Doesn't fully utilize ec's hash2curve module as k256 Scalar doesn't have FromOkm for some reason. The previously present bigint reduction is preserved. Updates ff/group to 0.12. Premised on https://github.com/cfrg/draft-irtf-cfrg-frost/pull/205 being merged, as while this Ed25519 is vector compliant, it's technically not spec compliant due to that conflict. 2022-06-06 06:18:25 +00:00			`group = "0.12"`
Add a batch verifier to multiexp, along with constant time variants Saves ~8% during FROST key gen, even with dropping a vartime for a constant time (as needed to be secure), as the new batch verifier is used where batch verification previously wasn't. The new multiexp API itself also offered a very slight performance boost, which may solely be a measurement error. Handles most of https://github.com/serai-dex/serai/issues/10. The blame function isn't binary searched nor randomly sorted yet. 2022-05-27 04:52:44 +00:00
