我们从一大类签名方案ℂ中给出了通用指定验证者签名方案的通用构造。由此产生的方案是有效的并且具有两个重要的特性。首先，它们被证明是 DV 不可伪造、不可转让且不可委托的。其次，签名者和指定验证者可以独立选择其密码设置。我们还从 ℂ 中的任何签名方案中提出了基于身份的签名方案的通用构造，并证明该构造对于自适应选择消息和身份攻击是安全的。我们讨论了我们的结构对通用多指定验证者签名、基于身份的分层签名、基于身份的通用指定验证者签名以及来自 ℂ 中任何签名的基于身份的环签名的可能扩展。
We give a generic construction for universal designated-verifier signature schemes from a large class, ℂ, of signature schemes. The resulting schemes are efficient and have two important properties. Firstly, they are provably DV-unforgeable, non-transferable and also non-delegatable. Secondly, the signer and the designated verifier can independently choose their cryptographic settings. We also propose a generic construction for identity-based signature schemes from any signature scheme in ℂ and prove that the construction is secure against adaptive chosen message and identity attacks. We discuss possible extensions of our constructions to universal multi-designated-verifier signatures, hierarchical identity-based signatures, identity-based universal designated verifier signatures, and identity-based ring signatures from any signature in ℂ.
