A survey: Spoofing attacks in physical layer security

Increasing demand on wireless communications also increases the issues related to communication security. Among different security solutions, physical layer security have recently been gaining many interests by the researchers. In this paper, a survey study is provided in one of the most critical attacks, namely spoofing attacks. When a legitimate transmitter stops sending a signal to a legitimate receiver, the spoofer starts to transmit a deceiving signal to the same legitimate receiver by acting as if it is the legitimate transmitter. The aim of the spoofer is to deceive the legitimate receiver. Within this concept, we first review the detection methods and countermeasures to spoofing attacks. To be able to evaluate the proposed techniques, we discuss different metrics provided in the literature. Then, we conclude the paper with the open issues.
