This paper describes a 1-out-of-N oblivious transfer (OT) extension protocol with active security, which achieves very low overhead on top of the passively secure protocol of Kolesnikov and Kumaresan (Crypto 2011). Our protocol obtains active security using a consistency check which requires only simple computation and has a communication overhead that is independent of the total number of OTs to be produced. We prove its security in both the random oracle model and the standard model, assumingdoi:10.1007/978-3-319-52153-4_22 fatcat:k2o5xndd4fbjtcgv6j77l3ycgq
