Universal designated-verifier signature allows a signature holder to designate the signature to a desire designated-verifier,in such a way only the designated verifier can verify this signature.Using the merits of Elliptic Curve Cryptosystem(ECC) and self-certified signcryption,a new self-certified universal designated-verifier signcryption based on ECC is presented.The scheme eliminates certificate existence problem and key escrow problem.It has low algorithm complexity,quick proceeding speed and little storage space,so it is propitious to applications in E-vote and E-auction.
