摘要：
Recently, Cao et al. presented a weak blind signature scheme based on a genuinely entangled six -qubit state. However, we find there exists a security problem that the receiver of the signature can forge a valid signature without being caught. In order to show that, the detailed attack strategy and the potential improved ideas are proposed in this paper.
