Ensuring the security of physical layer signals is crucial for maintaining the stability of all systems utilizing sensors.   Our primary goal is to develop detection and response systems to protect these signals, enabling sensor-based applications to operate more securely.

  Software security involves using security as a core principle in software design. The aim is to create software that remains secure and functional even during an attack. In the digital world, security means preventing unauthorized access to systems, software, and data.

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.

Like biometrics, we can measure inherent characteristics of a device. For instance, in wireless communication, devices transmit data by generating analog RF signals. Although the same data is transmitted, different devices produce slightly varied RF signals. This variation allows us to identify individual devices.
