Secrecy Energy Efficiency Maximization for RIS-Assisted UAV Communications via Joint 3D Trajectory and Passive Beamforming Design
Unmanned aerial vehicle (UAV) communications show great potential in establishing strong line-of-sight (LoS) links for ground users, which also leads to more susceptible terrestrial eavesdropping. Integrating a reconfigurable intelligent surface (RIS) into UAV communications offers a promising approach for secure trans...
