In this paper, we have investigated the application of continuous-variable quantum key distribution (CV-QKD) systems to provide keys for the AES-CTR algorithm. Constellation diagrams and bit error rates were used to visually demonstrate the impact of free-space optical (FSO) communication channels on the signal. Simulation results demonstrated that this method improve the security of FSO system evidently
