    In quantum communication, channel noise will affect the reliability and effectiveness of information transmission. Two controllable quantum dialogue(CQD) protocols are designed, which can resist collective-dephasing noise and collective-rotation dialogue noise respectively. The comparative analysis shows that the protocol can not only avoid the impact of collective noise, but also avoid information leakage, and effectively reduce the online time of the controller, and can resist external and internal attacks.
