Highly Efficient OT-Based Multiplication Protocols
Iftach Haitner and Nikolaos Makriyannis and Samuel Ranellucci and Eliad Tsfadia
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.
