Changelog

All notable changes to this repo will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

v1.8.0

• BLS12-381 is now constant time.
• BLS signatures use new CT-based version of the BLS12-381 curve.

v1.7.0

Fixed

• Fix an issue in the serialization wrapper for DKLs18 and generalizes the choice of the hash function.

v1.6.1

Fixed

• Fix an issue inherited from a transcription error in DKLs18, in which the KOS cOT extension subprotocol was implemented incorrectly.

v1.6.0

Add

• Constant time K256 curve.
• Constant time P256 curve.
• New DKLs18 implementation that fixes the issues in v0.
  • This also refactors OT, OT Extension, and Schnorr ZKP to their own packages.
  • Furthermore, this generalizes the input curve type of the protocol.
• Bulletproof IPP Prove and Verification functions.

Fixed

• nil check in paillier.Newpubkey.
