Abstract
A novel signature scheme based on DSA is proposed. When adding group member, parameters transferred between group member and group center were strengthened verified to ensure the information accurate. When deleting group member, modification to public key of group member was restricted to ensure that the deleted member was unable to sign. The parameters in the proposed scheme are less than 160 bits which is more efficient than the scheme based on RSA. Analysis shows that the proposed scheme satisfies security properties of the group signature.
