标准模型下基于身份的传递签名
摘要
基于waters的签名方案
提出了第一个基于身份的传递签名方案
方案被证明在标准模型下是安全的。与现有的传递签名方案相比
该方案将签名传递的不可伪造性归约到基于双线性配对的CDH问题上
并给出了方案的复杂度分析。
Abstract
Based on waters’ signature scheme
the first identity-based transitive signature scheme was proposed and proved secure against attacks in the standard model.Compared with current transitive signature schemes
the unforgeability of the signature’s transitivity of the proposed scheme was reduced to the CDH assumption based on the bilinear pairing.A complexity analysis of the proposed scheme was thereafter presented.
