摘要:

将子集覆盖框架与Camenisch-Stadler方案相结合,实现群成员的加入和撤销,且无需改变其他成员私钥,实现高效的签名验证效率。同时,在成员注册时增加一个知识签名,实现防联合攻击。分析表明,方案满足匿名性和抗联合攻击、伪造攻击和权威陷害攻击,并具有非关联性。效率方面,仅略增加群成员证书长度,达到常数级的签名和验证开销。

关键词: 群签名, 子集覆盖框架, 联合攻击, 非关联性

Abstract:

A group signature scheme which combines the subset cover framework with Camenisch-Stadler scheme was proposed.This scheme allowed any group members’ entrance and revocation without changing other members’ secret key.Meanwhile,the scheme added a knowledge signature while registering,that realized coalition resistance.It is shown that the scheme not only has the characteristics of anonymity and no-relation,but also can resist conspiracy attacks,forgery attack and authority trap attack.As for efficiency,the scheme just slightly increases the length of group members’ certificates,with the signature and verification complexity remaining at constant level.

Key words: group signature, subset cover framework, conspiracy attack, no-relation
