| 摘 要： | 该文提出了一个支持身份追踪的匿名认证方案。该方案有下列优点：(1)用户动态加入和吊销特别方便，管理员仅需在公告牌上公布和删除该成员的相关数据。(2)示证人可以灵活地、主动地选择匿名范围，即他可以任意选取多个合法的用户并说明自己在其中。(3)追踪示证人的具体身份是受限制的，管理员无法单独实现身份追踪，必须和验证者合作才能共同追踪示证人的身份。另外，在抵抗外部攻击和伪装攻击方面，该方案具有任意弹性，明显的优于Boneh(1999)的1-弹性方案。

| Abstract: | A new anonymous authentication scheme with traceable identity is proposed.This scheme has the following advantages:(1)It is easy for users to dynamically join and leave,the only thing needs to do is manager add or delete the relevant data of users.(2)The prover can unrestrictedly choose a group of users and declare that himself belong to it,so he can choose his anonymous scope initiatively and freely.(3)In the process of trace the identity of prover,the right of manager is restricted,he needs cooperation with the verifiers to reveal the identity of the prover.In the aspect of against outside attack and masking attack,compared with the scheme 1-resilient of Boneh(1999),this scheme can realize arbitrary resilience. |
