In this paper, based on Sigma-protocol on HC (a NP-complete language), we firstly construct a Sigma-protocol for any NP language thm1 ∧ thm2, then transfer it into a non-interactive protocol from a hash function and a pseudo-random generator. Finally, we construct an efficient round-optimal secure two-party computation protocol from our non-interactive… CONTINUE READING
