摘要

利用Waters的私钥构造方法提出了一个基于身份的环签名方案。该方案的安全性基于标准模型下的计算性Diffie-Hellman假设。对于有l个成员的环

签名长度只有l+1个群元素

签名验证需要l+1个双线性对运算。与现有的基于身份的环签名方相比具有较短的公开参数

且签名的效率进一步提高。

Abstract

An identity based ring signature scheme using the method of Waters for constructing private key was presented. This scheme is secure in the standard model under the computational Diffie-Hellman assumption. For l members of a ring

the signature consists of l+1 group elements and requires l+1 pairings to verify. It has shorter public parameter size and more efficiency compared with current signature scheme.
