An Efficient Secure Oblivious Transfer

Hung-Min Sun, Yalin Chen, and Jue-Sam Chou

Abstract

As traditional oblivious transfer protocols are treated as a cryptographic primitive, they are usually executed without the consideration of possible attacks, e.g., impersonation, replaying, and man-in-the-middle attacks. Therefore, when these protocols are applied in certain applications such as mental poker playing, some necessary mechanism must be executed first to ensure the security of subsequent communications. But doing this way, we found that almost all of the resulting mechanisms are not efficient enough in communicational cost which is a significant concern for commercial transactions. Inspired by these observations, we propose a novel secure oblivious transfer protocol based on bilinear pairing which not only can provide mutual authentication to resist malicious attacks but also is efficient in communicational cost, other than its original functions.
