Paper: ZKAttest: Ring and Group Signatures for Existing ECDSA Keys

Description

Enables ring and group signatures for existing ECDSA keys using zero-knowledge proofs. A party can prove membership in a group or ring without revealing which key they hold, using Pedersen commitments combined with SNARKs.

Properties

  • Completeness: Yes
  • Soundness: Computational
  • Zero-knowledge: Yes (which key is used is hidden)

Based on

Pedersen-Commitments, Sigma-Protocols-Damgard
