Title:
A novel k-out-of-n Oblivious Transfer Protocols Based on Bilinear Pairings

Authors: Yalin Chen, Jue-Sam Chou, Xian-Wu Hou

Abstract:

Low bandwidth consumption is an important issue in a busy commercial network whereas time may not be so crucial, for example, the end-of-day financial settlement for commercial transactions in a day. In this paper, we construct a secure and low bandwidth-consumption k-out-of-n oblivious transfer scheme based on bilinear pairings. We analyze the security and efficiency of our scheme and conclude that our scheme is more secure and efficient in communication bandwidth consumption than most of the other existing oblivious transfer schemes that we know.
