Oblivious transfer protocol with access control
YU Zhao-ping · Computer Engineering and Applications Journal · 2007
Based on ECC,a new oblivious transfer protocol with access control has been proposed in this paper.The proposed protocol has the property of oblivious transfer.Futhermore,the only receiver who has issued by the trust centre authority can open the message which they chose and the sender can not decide whether the receiver has been authenticated or not by the trust centre.The identity of the receiver can not be confirmed by the sender.Under the ECDLP assumption,the proposed scheme has provable security.This protocol has less data,faster and more applied value than others which are based on FFDLP.
