Highly efficient ot-based multiplication protocols
Annual International Conference on the Theory and Applications of …, 2022•Springer
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.

Abstract
We present a new -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.
