We extend the Tiny-OT two party protocol of Nielsen et al (CRYPTO 2012) to the case of
n
parties in the dishonest majority setting. This is done by presenting a novel way of transferring pairwise authentications into global authentications. As a by product we obtain a more efficient manner of producing globally authenticated shares, in the random oracle model, which in turn leads to a more efficient two party protocol than that of Nielsen et al.
