A new secure oblivious transfer(OT) protocol from indistinguishability obfuscation(iO) is proposed in this paper. The candidate iO and a dual-mode cryptosystem are the main technical tools of this scheme. Garg et al. introduced a candidate construction of iO in 2013. Following their steps, a new k-out-of-l OT protocol is presented here, and its realization from decisional Diffie-Hellman(DDH) is described in this paper, in which i O was combined with the dual-mode cryptosystem. The security of the scheme mainly relies on the indistinguishability of the obf-branches(corresponding to the two modes in dual-mode model). This paper explores a new way for the application of iO.
