A Group Signature Scheme Based on Elliptic Curve
Zecheng Wang · Jourmal of Tianzhong · 2002
In this article, a group signature scheme based on elliptic curve is proposed. With same security , the scheme is more efficient and the signature size is shorter .The scheme satisfies the basic requirements of group signature. The lengths of the group's public key and of the signatures, as well as the computational effort for signing and verifying, are independent of the number of group members. But the computational effort for opening is linear in the number of group members, so it is less efficient.
