| 摘 要： | 文章基于中国剩余定理,提出了一种改进的群签名方案。该方案在不改变其它有效成员的签名密钥的情况下,能够有效地增加或撤消一个群成员,并且签名的长度以及验证的工作量均独立于群成员和已删除的群成员的人数。该方案具有很好的不可链接性,而且其安全性是基于大数分解的困难性。

| Abstract: | In this paper,an improved group signature scheme based on Chinese Remainder Theorem is proposed.It allows the group manager to add new members or delete old members securely and effectively without changing other members' private keys.Furthermore,the length of the signature and the computational effort for signing and verifying are independent of the number of the group members and the deleted group members.The new solution is unlinkable and its security relies on the factoring of large integers. |
