摘要
匿名代理签名是特殊的代理签名,设计不需要可信任方参与的匿名代理签名方案是代理签名的一个重要研究方向。该文分析了两个该类方案的安全性,在此基础上给出了一个新的不需要可信任方的匿名代理签名方案。该方案具有强不可伪造性,且签名结果不含冗余数据。并以新方案为基础设计了两个匿名代理多重签名方案。
Anonymous proxy signature is one of the special proxy signatures. It is one of the important researches on the proxy signature that designs an anonymous proxy signature scheme without a trusted party. This paper analyzes the security of two schemes. Then a new anonymous proxy signature scheme without a trusted party is presented, which can keep the property of the strong unforgeability and does not have the redundant data in signature. In the end, two anonymous proxy multi-signature schemes based on the new scheme are designed.
