Efficient reduction of 1 out of $n$ oblivious transfers in random oracle model

Bao Li, Hongda Li, Guangwu Xu, and Haixia Xu

Abstract

We first present a protocol which reduces 1-out-of-$n$ oblivious transfer OT$_l^m$ to 1-out-of-$n$ oblivious transfer OT$_m^k$ for $n>2$ in random oracle model, and show that the protocol is secure against malicious sender and semi-honest receiver. Then, by employing a cut-and-choose technique, we obtain a variant of the basic protocol which is secure against a malicious receiver.
