Intelligent Wiretap Code Design: Exploiting Wireless Endogenous Security Via Information Theory and Deep Learning Integration

Recent advancements in wireless endogenous security have explored leveraging the inherent randomness of wireless channels to enhance communication security, providing an effective alternative to traditional encryption methods. This paper proposes a wiretap coding scheme within the semantic...

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...

Two-Way Wiretap Channel under Mixed Secrecy Constraint

This paper studies the two-way wiretap channel TW-WC with an external eavesdropper under strong one-sided mixed secrecy: only User1's message is required to be secure from the eavesdropper, while no secrecy constraint is imposed on User2's message. Secrecy is measured by the information leakage o...

Cryptographic and Information-Theoretic Security Capacities for General Arbitrarily Varying Wiretap Channels

We compare the strong secrecy capacities of Arbitrarily Varying Wiretap Channels AVWCs and General Arbitrary Varying Wiretap Channels GAVWCs with their capacities under semantic secrecy constraint and other equivalent cryptographic secrecy constraints. It turns out that the average error and stro...

Hackers may have breached FBI wiretap network via supply chain

Investigators are worried that a recent attack on a critical FBI system was more than just a random hit, and that another nation-state might have been involved. On February 17, the FBI flagged irregular network activity that led straight to its Digital Collection System Network. That system...

Artificial Noise Versus Artificial Noise Elimination: Redefining Scaling Laws of Physical Layer Security

Artificial noise AN is a key physical-layer security scheme for wireless communications over multiple-input multiple-output wiretap channels. Recently, artificial noise elimination ANE has emerged as a strategy to mitigate the impact of AN on eavesdroppers. However, the influence of ANE on the...

Secure Integrated Sensing and Communication against Communication and Sensing Eavesdropping

Sensing privacy and communication confidentiality play fundamentally different but interconnected roles in adversarial wireless environments. Capturing this interplay within a single physical-layer framework is particularly challenging in integrated sensing and communication ISAC systems, where t...

Helper-Assisted Coding for Gaussian Wiretap Channels: Deep Learning Meets PhySec

Consider the Gaussian wiretap channel, where a transmitter wishes to send a confidential message to a legitimate receiver in the presence of an eavesdropper. It is well known that if the eavesdropper experiences less channel noise than the legitimate receiver, then it is impossible for the...

Experts tell US lawmakers that a crucial spy program’s safeguards are failing, allowing intel agencies deeper, unconstrained access to Americans’ data...

An Efficient Secret Communication Scheme for the Bosonic Wiretap Channel

We propose a new secret communication scheme over the bosonic wiretap channel. It uses readily available hardware such as lasers and direct photodetectors. The scheme is based on randomness extractors, pulse-position modulation, and Reed-Solomon codes and is therefore computationally efficient. I...

A DRL-Empowered Multi-Level Jamming Approach for Secure Semantic Communication
