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.
