| Abstract: | Without the use of computational assumptions, unconditionally secure oblivious transfer (OT) is impossible in the standard model where the parties are using a clear channel. Such impossibilities can be overcome by using a noisy channel. Recently, Palmieri and Pereira proposed a protocol based on random channel delays only. Their scheme is secure in the semi-honest model, but not in the general malicious model. In this paper we study oblivious transfer in the same setting but we improve the result to obtain a fully secure protocol in the malicious model. |
