Abstract: We analyze PHY-layer authentication in wireless networks, which employs radiochannel information (such as received signal strength indicators) to detect spoofing attacks.A zero-sum authentication game is often used to represent the interactions between a legitreceiver and spoofers. The receiver picks the hypothesis test threshold to maximize its utility based on the Bayesian risk in spoofing detection, while the spoofers choose their attackpatterns to lower the receiver’s utility. The static authentication game’s Nash equilibrium isderived, and its uniqueness is explored. In a dynamic radio environment, we also study a recurrent PHY-layer authentication game. As tough as it is, to retrieve the correct channelparameters in the radio nodes. We suggest spoofing in advance. A CPS is a mixture ofsophisticated control, awareness, computing, and communication systems. The variety andcomplexity of CPs have revealed potential security and resilience problems. The integrationof bulk physical layer components makes it more difficult to protect against physicalvulnerabilities. Cyber-integration, on the other hand, which relies on network connectivityand internet of things(IoT) based devices, necessitates significant investments in securitydesigns and upgrade to protect against unanticipated cyber-threats.
