A new arbitrated quantum signature of quantum messages with a semi-honest arbitrator is designed by utilizing the chained control-NOT(CNOT) operations encryption and the classical public board. Detailed theoretical analysis show that the proposed scheme satisfies the requirements of unforgeable and undeniable properties. The novelty is that the feasibility of signing quantum messages under the control of a semi-honest arbitrator is demonstrated. And with the help of the decoy technique, shared keys can be reused.
