Information Leakage Rate of Optical Code Division Multiple Access Network Using Wiretap Code
Entropy, 2023 Secrecy capacity is usually employed as the performance metric of the physical layer security in fiber-optic wiretap channels. However, secrecy capacity can only qualitatively evaluate the physical layer security, and it cannot quantitatively evaluate ...

Exploiting the physical in cyber-physical systems: On the practical use of physical-layer information to enhance system security [PDF]
, 2022 This thesis argues that cyber-physical systems are, by their very nature, at risk from physical-layer attacks as well as cyber attacks. The proliferation of cheap and easy-to-use sensing and actuation technologies has drastically lowered the bar for ...

Techniques for Enhanced Physical-Layer Security [PDF]
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010 Information-theoretic security--widely accepted as the strictest notion of security--relies on channel coding techniques that exploit the inherent randomness of propagation channels to strengthen the security of communications systems. Within this paradigm, we explore strategies to improve secure connectivity in a wireless network.

Quantum security for the physical layer [PDF]
IEEE Communications Magazine, 2013 The physical layer describes how communication signals are encoded and transmitted across a channel. Physical security often requires either restricting access to the channel or performing periodic manual inspections. In this tutorial, we describe how the field of quantum communication offers new techniques for securing the physical layer.
