一个强指定验证者签名的构造方案

指出了已有的几个私有指定验证者签名方案的共有特征。这些方案遵循了共同的设计思路:某种意义上讲,它们都可以看作消息认证码,而其私钥则是通过著名的Diffie-Hellman协议生成的。利用同样的设计框架,给出了私有指定验证者签名方案的一种模块化的设计方案,并且这些方案可以达到更好的效率。

Efficient Constrution of Strong Designated Verifier Signature

A common characteristic of some private designated verifier signature schemes is point out.Underlying these is a overlooked framework:in some sense,they are all message authentication code schemes(MAC)with the private key generated through the famous Diffie-Hellman protocol.With this framework,be can modularly construct private designated verifier signature schemes which are much more efficient than the previous ones.
