Physical layer (PHY) authentication based on the unique channel properties has proven effective due to its simple, fast, and distributed procedures with the recent explosion of the Internet of things (IoT) devices. Authentication is the process of verifying identity claims. If an intruder collects confidential information on wireless links and sends a forged signal, it can cause serious problems. Through an authentication protocol, which verifies the identities of both parties over the wireless link and then establishes a common secret key between them, these threats can be reduced or even completely eliminated. Consistently the conventional cryptographic security mechanisms have been used to prevent intelligent attacks (e.g., impersonation attack). Although the effectiveness of these cryptography-based authentication mechanisms have been proven, proper key management and distribution which may cause large signaling overhead in a large scale network (e.g., Internet of things (IoT)) are required.
