We present a new protocol for maliciously secure two-party computation based on cut-and-choose of garbled circuits using the recent idea of “forgeand-loose”, which eliminates around a factor 3 of garbled circuits that needs to be constructed and evaluated. Our protocol introduces a new way to realize the “forge-and-loose” approach, which avoids an auxiliary secure two-party computation protocol, does not rely on any number theoretic assumptions and parallelizes well in a same instruction… CONTINUE READING
