  • Based on RSA signature and (string) oblivious transfer, an oblivious transfer protocol is proposed which solved the access control problem for an oblivious transfer protocol. The protocol proposed has the property: the only receiver who has the signature issued by the central authority can open the message which he chose; the sender can not decide whether the receiver has the signature or not. That is the identity of the receiver can not be confirmed after the protocol. Under the Decisional Diffie-Hellman(DDH) assumption the proposed scheme has provable security. The proposed scheme employs the standard RSA signature and Elgamal encryption.
