Phy-layer Security

PHY-layer security (Physical Layer Security) refers to techniques and methods used to secure wireless communication at the physical layer of the communication protocol stack. Unlike traditional cryptographic approaches that focus on securing data at higher layers (e.g., network or application layer), PHY-layer security aims to exploit the characteristics of the wireless channel itself to provide security services such as confidentiality, authentication, and integrity.
