Abstract :
In this paper, based on bilinear pairings, we propose a new identity-based strong designated verifier signature scheme, in which two independent PKGs are introduced to solve the secure trouble that the single PKG can impersonate the signer to forge legal signatures. With analyzing, we find our scheme has many other secure characters, such as, strongness, nontransfer ability privacy, unforgeability.
