Abstract

Radio frequency (RF) signals propagate through most materials that we are surrounded by while light is blocked by many of these materials. This feature makes wireless networks based on light (which are also referred to as LiFi networks) inherently more secure. However, it can also lead to sudden link failure if the legitimate data link is blocked because of user movements or changes in device orientation. In this paper, the secrecy capacity has been analysed with the consideration of imperfect channel state information, random device orientation and probability of link blockage for the case of a single eavesdropper. It has been found that the secrecy capacity almost doubles in a standing activity as opposed to a sitting activity and that the density of blocking objects degrades the secrecy capacity in single access point networks. It is evident that environmental factors and user behaviour have a significant impact on the secrecy performance and, thus, need to be considered for robust physical layer security (PLS) design in LiFi networks.
