Aiming at the physical layer security (PLS) secure transmission existing in the information back-haul link of the satellite-UAV integrated (SUI) net-work, a two-layer Stackelberg game model (TSGM) that can resist full-duplex (FD) eavesdropping and jamming attacks is proposed. The confrontation re-lationship between the UAV network and the attacker is established as the first layer Stackelberg game. The source UAV adjusts its own transmission power strat-egy according to the attacker's jamming strategy to re-sist malicious jamming attacks. The internal compe-tition and cooperation relationship in UAV network is modeled as the second layer Stackelberg game, and the optimal cooperative UAV transmits jamming signal to the attacker to resist malicious eavesdropping attacks. Aiming at the"selfishness"of UAV nodes, a price in-centive mechanism is established to encourage UAV to actively participate in cooperation, so as to maximize the advantages of cooperative communication. For the proposed TSGM, we construct the utility function and analyze the closed equilibrium solution of the game model, and design a three-stage optimal response iter-ative (TORI) algorithm to solve the game equilibrium. The simulation results show that the proposed TSGM can effectively increase the utility of the source UAV and improve the enthusiasm of cooperation compared with other power control models.
