Abstract: In order to solve the problem that KGC can not be trusted in ID-based group signature,a new ID-based dynamic group signature scheme is proposed.The new verify and open algorithms make sure the scheme can against forgery attack.Additional,this scheme can delete members simply and efficiently without changing the group public key and the other group members’ key.At the same time,the sizes of signature and key are independent on the numbers of the group members.

Key words: group signature, ID-based, dynamic

摘要: 为了解决在基于身份的群签名中KGC不可信的问题,提出了一种新的基于身份的动态群签名方案。新的验证和打开算法确保了该方案可以抵抗伪造攻击。另外该方案可以简单有效地删除群成员,而不改变群公钥和其他群成员的密钥,签名和密钥的长度不依赖于群成员的个数。
