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.
