Abstract

Naor and Pinkas (1999a) pointed out that 'this is of interest, given the possibility of implementing Oblivious Transfer using physical means, e.g., via a noisy channel or quantum cryptography. However, some of these reductions are not particularly efficient. .. '. Using tamper-proof smart cards, we propose some radically different approaches to the Oblivious Transfer problem. Despite the simplicity of our model, we achieve unconditional security and privacy for both the sender and receiver. In contrast to all known oblivious transfer protocols, which require extensive computations, the proposed schemes are very computationally efficient.
