| 摘 要： | 文章在(t,n)门限秘密共享的基础上提出了一种动态的数字签名认证方案.该方案无需可信中心,组内所有成员共同生成组私钥,至少t个合法成员才可以产生签名证书；可以动态增加或者删除成员而无须改变组私钥,减小了方案实施的代价,实现了组成员的动态管理；经过分析,证明了该方案的正确性和安全性.

| Abstract: | A dynamic digital signature authentication scheme without a trusted party is proposed based on(t,n) threshold secret sharing.All of the group members together generate the group's private key and at least t members can generate the signature certificate.The members are allowed to join or leave without changing the group's private key,which are managed dynamically.The scheme is proved to be safe,correct and easier to implement. |
