| 摘 要： | 高级门限群签名是门限群签名的扩展。本方案中用的高级门限思想是两个群体（可以是敌对的）共享一个秘密，只有两者共享各自的秘密份额，才能完成有效的签名。对消息M的签名采用一种改进的RSA签名方法。在文章的最后对此方案进行了正确性和安全性分析，证明本文提出的方案有一定的应用价值。

| Abstract: | Advanced threshold group signature is the extended version of threshold group. Both groups can share one secret ,and only both of them share their shares can they complete the effective signature. This is what the advanced threshold idea is used in this paper. A kind of improved RSA signature is applied on mes- sage M to carry out signature. Finally, the validity and security are analysed, proving the usefulness of this schcme. |
