This paper studies the design of energy-efficient artificial noise (AN) schemes in the context
of physical layer security in visible light communications (VLC). Two different transmission …

We consider the physical layer security (PLS) of multi-user (MU) multiple-input-multiple-
output visible light communication (VLC) systems with an eavesdropper (Eve) and propose …

Physical layer security (PLS) has recently gained a lot of attention in the research and
development of visible light communication (VLC). In this article, we study the designs of …

There has been an increasing interest in physical layer security (PLS), which, compared with
conventional cryptography, offers a unique approach to guaranteeing information …

Recently, physical-layer encryption was featured as a favorable security method for visible
light communications (VLCs). Generally, orthogonal frequency-division multiplexing (OFDM) …
