摘要

群签名方案存在着管理员权利过大的缺点

而环签名方案又无法追踪签名人的身份

本文利用环签名的思想提出的一个新的类似群签名的匿名签名方案解决了这一矛盾.和已有的群签名方案相比

该方案因保留了环签名的部分特性而具有如下优点:(1)管理员的权限得到了限制

他必须和签名接收方合作才能共同追踪签名者的身份;(2)签名者可以灵活地、主动地选择匿名范围

即他可以任意选取

个合法的公钥说明自己在其中;(3)用户加入和撤销特别方便

管理员仅需在公告牌上公布和删除该成员的相关数据.

Abstract

Traditional group signatures have the demerit that the group manager has the absolute power in revoking the signer's identity.The unconditional anonymity of ring signature provides chances for the criminals.We give a new group signature scheme based on the idea of ring signature.Compared with the old ones

this scheme has the following advantages:(1)The right of the group manager is restricted

he can only revoke the identity of the signer with the receiver's co-operation.(2)The signer can choose the public keys he wants to realize his anonymous scope.(3)Easy for users to join and leave

it only needs the group manager to add or delete the public key of the corresponding user.
