An identity-based strong designated verifier proxy signature scheme
Wang Qin, Cao Zhenfu · Wuhan University Journal of Natural Sciences · 2006
In a strong designated verifier proxy signature scheme, a proxy signer can generate proxy signature on behalf of an original signer, but only the designated verfier can verify the validity of the proxy signature. In this paper, we first define the security requirements for strong designated verifier proxy signature schemes. And then we construct an identitybased strong designated verifier proxy signature scheme. We argue that the proposed scheme satisfies all of the security requirements.
