Efficient reduction of 1 out of n oblivious transfers in random oracle model.
Bao Li, Hongda Li, Guangwu Xu, Haixia Xu · 2005
We first present a protocol which reduces 1-of-n oblivious transfer OT m 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.
