一种与身份有关的群签名方案

An identity-based group signature scheme

本文参照 Jae Choon Cha 和 Jung Hee Cheon的一种基于身份的数字签名方案[1],提出了一种新的与身份有关的群签名方案。该方案基于CDHP的难解性和DDHP的可计算性,它满足群签名的基本特性。

In this paper, I refer to Jae Choon Cha and Jung Hee Cheon about an identity-based signature from gap diffie-hellman groups, and propose a new identity-based group signature scheme. This scheme is base on difficulty of CDHP and calculability of DDHP, and it is provided with the main properties of group signature.
