作者从一大类签名方案（称为 Class ℂ）中给出了通用（多）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。作者还提出了基于 ℂ 中任何签名方案的（分层）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。作者讨论了我们的结构可能扩展到基于身份的环签名和基于身份的指定验证者签名（来自 ℂ 中的任何签名）。最后，作者表明可以组合上述结构来获得具有组合功能的签名。
The authors give a generic construction for universal (mutli) designated-verifier signature schemes from a large class of signature schemes, referred to as Class ℂ. 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. The authors also propose a generic construction for (hierarchical) identity-based signature schemes from any signature scheme in ℂ and prove that the construction is secure against adaptive chosen message and identity attacks. The authors discuss possible extensions of our constructions to identity-based ring signatures and identity-based designated-verifier signatures from any signature in ℂ. Finally, the authors show that it is possible to combine the above constructions to obtain signatures with combined functionalities.
