Protocol Integration of Physical Layer Deception into EAP-TEAP Wi-Fi Authentication

Credential-based Extensible Authentication Protocol EAP authentication cannot distinguish a legitimate credential holder from an adversary using compromised credentials. Physical Layer Deception PLD complements credential-based authentication by exposing a deceptive primary object over a primary...

Backward-Compatible Tag-Based PHY Authentication for Secure WLAN Sensing

Driven by ongoing standardization efforts, Wi-Fi sensing has recently emerged as a promising functionality within wireless local area networks WLANs. However, due to the use of standard null-data packets NDPs to estimate the channel, conventional Wi-Fi sensing systems are susceptible to spoofing...

Unlocking Cross-Scenario Physical Layer Security: A Mixture-Of-Experts Framework with Generative Diffusion Models

The future 6G networks are expected to incorporate a proliferation of wireless services in diverse environments, which presents a significant challenge for information security. Conventionally optimization always requires recalculation and learning strategy often suffers poor generalization, whic...

Variational Probabilistic Quantization for Secret Key Generation

Secret key generation from correlated observations at Alice and Bob, in the presence of an eavesdropper Eve, underpins physical-layer security. Classical pipelines quantize by hand, amplify privacy afterwards, and optimize no objective tied to a key rate. We propose Variational Probabilistic...

Security-Aware Pinching-Antenna Systems (PASS): Physical-Layer Security Transmission

This paper investigates heterogeneous secure multi-user transmission in pinching-antenna systems PASS, where dynamically adjustable pinching antennas reshape both guided-wave and free-space propagation to improve communication and confidentiality performance. Unlike conventional physical-layer...

MARL-Based Sequential RIS Auctions: A Physical-Layer Security Analysis

Reconfigurable intelligent surfaces RISs hold great potential to enhance coverage, spectral efficiency, and communication security by intelligently configuring their reflecting elements. When owned by a neutral RIS operator, these elements can be offered as resources for which legitimate receiver...

Sub-Vacuum Jamming for Secure Communication

Artificial-noise jamming improves physical-layer security by degrading an eavesdropper's channel, but the injected noise also interferes with the legitimate receiver. We introduce a correlated-jamming protocol based on classical and quantum correlations that suppresses this self-interference whil...

Quantum-Enhanced Physical-Layer Threat Detection in Metropolitan-Scale Fiber Networks

Network security is widely recognized as a key application of quantum technology. However, its large-scale deployment is hindered by the need for tight coordination between fundamentally different quantum and classical processing steps in conventional protocols. This requirement introduces strong...

Entropy-Adaptive Multi-Map Chaotic Modulation for Physical-Layer Security

This paper presents a Multi-Map Dynamic-Entropy Intrusion-Aware Chaotic Modulation MU-DE-IAEACM-MM framework for adaptive physical-layer security in multi-user wireless systems. Unlike conventional chaos-based schemes that rely on static parameter secrecy, the proposed architecture treats entropy...

Security Analysis of RIS-Assisted Physical-Layer Authentication over Multipath Channels

In physical layer authentication, verification of a user's identity is based on the characteristics of the transmission channel through which signals are delivered to the authenticator Bob. In this paper, we assume that the signals received by Bob pass through a \acRIS controlled by Bob and that...

CVE-2026-53232

A flaw was found in the Linux kernel's network PHY Physical Layer driver. When a PHY probing operation fails, the system does not properly clean up the SFP Small Form-Factor Pluggable upstream connection. This oversight leaves a dangling reference in the SFP bus, which could be accessed later...
