Title:
High Performance Multi-Party Computation for Binary Circuits Based on Oblivious Transfer

Abstract:We present a unified view of the two-party and multi-party computation protocols based on oblivious transfer first outlined in Nielsen \emph{et al.} (CRYPTO 2012) and Larraia et al. (CRYPTO 2014). We present a number of modifications and improvements to these earlier presentations, as well as full proofs of the entire protocol. Improvements include a unified pre-processing and online MAC methodology, mechanisms to pass between different MAC variants, and fixing a minor bug in the protocol of Larraia \emph{et al.}~in relation to a selective failure attack. It also fixes a minor bug in Nielsen \emph{et al.} resulting from using Jensen’s inequality in the wrong direction in an analysis.
