N2 - The broadcast nature of wireless networks makes them vulnerable to eavesdropping attacks; therefore, physical layer security (PLS) becomes essential to protect the signal at the physical layer. In this paper, we investigate PLS aspects in terms of the secrecy capacity (SC) in hybrid radio frequency (RF)/visible light communication (VLC) networks. First, we design RF-and VLC-based beamforming vectors to maximize the achievable SC. Moreover, using these vectors, we solve the power minimization problem satisfying the required SC. The results provide useful insights into how the eavesdropper's location affects the power consumption profile. Finally, the results reveal that the performance of the VLC network in terms of the consumed power per bits/s/Hz is more efficient than the RF one.
