该文提出了一种新的基于身份的环签名方案,并在标准模型下证明其能抵抗签名伪造攻击,且具有无条件匿名性.与现有标准模型下基于身份的环签名方案相比,新方案具有更短的公开参数,对于个成员的环,签名长度只有个群元素,签名验证需要个双线性对运算,因此能更好的满足应用要求.

A new identity-based ring signature scheme is proposed. This scheme is existentially unforgeable in the standard model and unconditionally anonymous. Compared with the existing identity-based ring signature schemes in the standard model, this new scheme has shorter public parameter size, moreover, for members of a ring, the signature only consists of group elements and needs pairings to verify, thus it can more satisfy the application requirements.
