Summary:The invention discloses a wireless communication confrontation system optimization method and device based on a reconfigurable intelligent surface, and the method comprises the steps: obtaining channel fading gains among nodes based on a wireless communication confrontation system, obtaining a receiving signal of an illegal receiver according to the channel fading gains among the nodes, and carrying out the optimization of a wireless communication confrontation system based on the receiving signal. Calculating a receiving signal-to-noise ratio of an illegal receiver; according to the optimization problem with minimization of the receiving signal-to-noise ratio of an illegal receiver as a target, a wireless communication countermeasure system optimization model is constructed with the phase and amplitude of each reflection unit of a reconfigurable intelligent surface RIS node as constraints; and based on a wireless communication countermeasure system optimization model, jointly optimizing the phase and the amp
