A new scheme of dynamic group blind signature based on elliptic curve discrete logarithm problem (ECDLP) which extends the dynamic group blind signature and the knowledge signature to the elliptic curve cyclic group is generalized. The scheme runs in time slice manner and can be proved security with zero knowledge proof. It supports the dynamic addition and deletion of the group members freely. And the length of signature and computational effort for signing and verifying are independent on both the number of group members and the deleted members. So the security and efficiency are enhanced.
