A Two-Party Protocol with Trusted Initializer for Computing the Inner Product

Rafael Dowsley, Jeroen van de Graaf, Davidson Marques, and Anderson C. A. Nascimento

Abstract

We propose the first protocol for securely computing the inner product modulo an integer $m$ between two distrustful parties based on a trusted initializer, i.e. a trusted party that interacts with the players solely during a setup phase. We obtain a very simple protocol with universally composable security. As an application of our protocol, we obtain a solution for securely computing linear equations.
