Abstract
This thesis addresses physical layer security issues for visible light communication
(VLC) systems and proposes use of intelligent reflective surfaces (ISRs) to
improve security. A scenario with a transmitter such as a ceiling light, a legitimate
receiver, and an eavesdropper is considered for an indoor space. In the scenario, IRS
that is mounted on the wall constantly changes the characteristics of the multipath
channel so that any attempts of the eavesdropper to estimate the channel and intercept
data would be futile. The work demonstrates the efficiency of the proposed
method through numerical simulations by evaluating the bit-error rates of the users
and secrecy capacity of the system.
The thesis dives into one of the latest and most promising technologies, visible
light communications (VLC), and the ways of securing it from eavesdroppers. In
this work, IRS protects the channel from the eavesdroppers on the physical layer of
communications systems. The given thesis considers a practical real-world scenario,
simulates the system’s performance, and thoroughly discusses the results. The initial
findings indicate that the use of IRS offers a promising approach to safeguard communication
against eavesdroppers who may attempt to exploit channel estimation
to breach the system’s secrecy capacity.
