Abstract
By integrating the thought of self-certified signcryption and universal designated-verifier signature,the first self-certified universal designated-verifier signcryption scheme is proposed and proved to be secure under the hardness of elliptic curve discrete logarithm problem and bilinear Diffie-Hellman problem.The new scheme allows the signcryption holder to designate the signcryption to a desire designated verifier,in such a way that only designated verifier can verify this signcryption,moreover,it overcomes certificate management problem and key escrow problem,and it has the merits of lower storage space and better security,so it has very practical value in E-commerce and E-governmemt.
