Efficient Zero-Knowledge Arguments in Discrete Logarithm Setting: Sublogarithmic Proof or Sublinear Verifier 📺
Sungwook Kim Hyeonbum Lee Jae Hong Seo
We propose three interactive zero-knowledge arguments for arithmetic circuit of size N in the common random string model, which can be converted to be non-interactive by Fiat-Shamir heuristics in the random oracle model. First argument features O( log N ) communication and round complexities and O(N) computational complexity for the verifier. Second argument features O(log N ) communication and O( N ) computational complexity for the verifier. Third argument features O(log N ) communication and O( N log N ) computational complexity for the verifier. Contrary to first and second arguments, the third argument is free of reliance on pairing-friendly elliptic curves. The soundness of three arguments is proven under the standard discrete logarithm and/or the double pairing assumption, which is at least as reliable as the decisional Diffie-Hellman assumption.
