  Physical Layer Security (PLS) is an emerging concept in the field of secrecy
for wireless communications that can be used alongside cryptography to prevent
unauthorized devices from eavesdropping a legitimate transmission. It offers
low computational cost and overhead by injecting an interfering signal in the
wiretap channels of potential eavesdroppers. This paper discusses the benefits
of the Artificial Noise and Cooperative Jamming techniques in the context of
Vehicle-to-everything (V2X) networks, which require secure data exchange with
small latency. The simulations indicate that messages can be safely delivered
even with devices that have low available power.
