摘要
摘要:属性基群签名(ABGS)是一类特殊形式的群签名,其允许拥有某些特定属性的群成员匿名地代表整个群对消息进行签名;当有争议发生时,签名打开实体可以有效地追踪出真实签名者。针对格上第1个支持本地验证者撤销的属性基群签名群公钥尺寸过长,空间效率不高的问题,该文采用仅需固定矩阵个数的紧凑的身份编码技术对群成员身份信息进行编码,使得群公钥尺寸与群成员个数无关;进一步地,给出新的Stern类统计零知识证明协议,该协议可以有效地证明群成员的签名特权,而其撤销标签则通过单向和单射的带误差学习函数来进行承诺。

Abstract:Attribute-Based Group Signature(ABGS) is a new variant of group signature, and it allows group members with certain specific attributes to sign messages on behalf of the whole group anonymously; Once any dispute arises, an opening authority can effectively reveal and track the real identity information of the singer. For the problem that the first lattice-based attribute-based group signature scheme with verifier-local revocation has a long bit-size of group public-key, and thus a low space efficiency, a compact identity-encoding technique which only needs a fixed number of matrices is adopted to encode the identity information of group members, so that the bit-size of group public-key is independent of the number of group members. Moreover, a new Stern-like statistical zero-knowledge proofs protocol is proposed, which can effectively prove the member’s signature privilege, and its revocation-token is bound to a one-way and injective learning with errors function.
