Universal designated multi verifier signature scheme without random oracles
Yang Ming, Yumin Wang · Wuhan University Journal of Natural Sciences · 2008
In this paper, we re-formalize the security notions of universal designated multi verifier signature (UDMVS) schemes. Then the first UDMVS scheme is presented in the standard model (i.e. without random oracles) based on Waters’ signature scheme. In this setting, a signature holder can to designate the signature to multi verifiers. Moreover, the security of our proposed scheme is based on the Gap Bilinear Diffie-Hellman assumption.
