Overview

This work introduces time-release zero-knowledge proofs, improving verification and authentication in cryptographic systems.

Key Points

  • The study aims to introduce and formalize a novel time-release zero-knowledge proof (TRZKP) concept.
  • Introduced the concept of TRZKP as a non-interactive zero-knowledge proof.
  • Developed light constructions for time-release versions of NIZKs using Fiat-Shamir transformation.
  • Conducted theoretical and practical analyses comparing TRZKP to existing verifiable timed signatures (VTS).
  • TRZKP offers significant improvements in verification time, reducing it from seconds to milliseconds.
  • The signing time of VTS remains nearly unchanged despite increased delay times.
  • The size of VTS produced is 67 times smaller than existing state-of-the-art solutions not using TRZKP.
