In this paper, we first study the cryptanalysis of quantum signature scheme based asymmetric quantum cryptography . Then the results of analysis show that quantum signature scheme exits the forgery attack. Finally, we give some suggests used to improve the above scheme, for example, a security detection mechanism should be performed in the above schemes. Furthermore, this quantum signature scheme also can withstand the forgery attack by adding a random positive integer shared in between the signer and the verifier.
