A Secure Oblivious Transfer Protocol from Indistinguishing Obfuscation

Mei Wang, Zheng Yuan, and Xiao Feng

Abstract

We proposed a new secure oblivious transfer protocol from indistinguishability obfuscation in this paper. Our main technical tool is the candidate indistinguishability obfuscation introduced in [1] and a dual-mode cryptosystem proposed in [2]. Following their steps, we presents a new k-out-of-l oblivious transfer protocol, its realization from DDH is described in this paper, in which we combined indistinguishability obfuscation with the dual-mode cryptosystem. The security of our scheme mainly relies on the indistinguishability of the obf-branches ( corresponding to the two modes in dual-mode model). Our paper explores a new way for the application of indistinguishability obfuscation.
