We present a unified view of the two-party and multi-party computation protocols based on oblivious transfer first outlined in Nielsen et al and Larraia et al. 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 methodologies, fixing a minor bug in the protocol of Larraia et al in relation to a selective failure attack.
