A quantum information signature protocol based on weak nonlinearity and the symmetrical quantum cryptography is proposed. A sender can send classical messages and can judge whether the messages have been modified or replaced by an adversary. When the authentication of messages is completed, the fact of the communication can neither be disavowed by the sender nor be denied by the receiver because of the existence of an honest arbitrator.
