Web3 Mar 2024 · Goldwasser Micali encrypts a 0 by sending a quadratic residue and a 1 by sending a non-quadratic residue. So, to prove that the encrypted bit is 0 what you need is a zero-knowledge proof of quadratic residuosity: for a given b, N, does there exist an a such that a 2 = y mod N. There exist such proofs, and it should be easy to find online.
