| 摘 要： | 提出了一个有效的群签名方案,它的公开密钥与签名长度不随群成员数量的变化而变化.该群签名方案在增加新成员时,无需修改群的公开密钥.并且在RSA假设与决定性的Diffie Hellman假设下,群签名方案是安全的,且能够抵抗联合攻击.

| Abstract: | In this paper, we propose an efficient group signature scheme whose public key and signatureshave length independent of the number of group members and which allows the group manager to add newmembers to the group without modifying the public key.Furthermore, our scheme is secure and coalitionresistantunder the RSA assumption and the decisional Diffie-Hellman assumption. |

| Keywords: | signature of knowledge e-th root of discrete logarithm group signature coalitionresistance |
