摘要 根据新的零知识证明方案,结合多项式的性质提出了一个群签名方案,该方案通过新的方法验证群成员身份,将成员信息与特殊多项式结合,不但防止了恶性攻击,而且通过验证多项式根来完成群内成员的删除,方案有较高的安全性。 This paper combining with a new zero-knowledge proof scheme proposes a group signature scheme,which uses property of polynomial, combining information of members of group with special polynomial,not only prevents malignant attack,but also confirms ID of members of group and deletes members of group by verifying polynomial-roots.It has higher security.
