Abstract

We present a new OT -based two-party multiplication protocol that is almost as efficient as Gilboa’s semi-honest protocol (Crypto ’99), but has a high-level of security against malicious adversaries without further compilation. The achieved security suffices for many applications, and, assuming DDH, can be cheaply compiled into full security.
