摘要 根据Gennaro等提出的分布式密钥生成协议,基于Boneh-Shen-Waters(BSW)签名方案提出了一种标准模型下强不可伪造门限签名。该方案基于一般的困难问题假设计算Diffie-Hellman问题。由于BSW方案无法直接转化为门限签名,本文方案通过加入了一个可信第三方实现转换。 In this paper,the authors propose a strongly unforgeable threshold signature scheme using Gennaro＇s distributed key generation protocol and based on Boneh-Shen-Waters（BSW） signature scheme.Its security is based on Computational Diffie-Hellman（CDH） assumption.Because BSW scheme can not transfer to a threshold signature directly,a trusted third part is added to realize the transformation.
