In this study, the technology of active reconfigurable intelligent surface (RIS) is employed to devise a secure communication strategy suitable for a dual unmanned aerial vehicle (UAV) environment. Under this strategy, one UAV is tasked with conveying information to the user, while the other UAV is responsible for transmitting interference signals to disrupt the eavesdropper, ensuring the security of communication between the UAV and the legitimate receiver. The problem is classified as a non-convex optimization issue, and through collaborative optimization of the UAV’s transmission power, interference power, flight path, and the coefficient matrix of RIS, the optimal average secrecy rate of the strategy can be derived. In addition, the introduction of successive convex approximation and semidefinite relaxation simplify the objective function into a more manageable form. Meanwhile, a penalty-based method is used to solve the rank-one problem. Simulation results demonstrate that the Active RIS technology can significantly enhance the performance of the dual UAV secure communication system.
