Do Electromagnetic Side-Channel Attacks Threaten Electronic Polling Stations? Scenarios and Recommendations

This paper investigates the threat to ballot secrecy in the Brazilian electronic voting machine UEB posed by electromagnetic side-channel attacks, also known as TEMPEST attacks. In these attacks, screen content can be reconstructed remotely by intercepting electromagnetic emanations associated wi...

Secure ISAC with Sensing Privacy under Eavesdropper Uncertainty

This paper investigates the joint protection of confidential data and legitimate-user directional information in integrated sensing and communication ISAC networks. We consider a multiuser downlink in which passive multi-antenna eavesdroppers Eves attempt to decode confidential signals while...

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...

Tracking-Assisted Robust Secure Transmission against a Mobile Eavesdropper in Cell-Free ISAC Networks

In this paper, we propose a tracking-assisted robust secure transmission framework for cell-free integrated sensing and communication ISAC networks that exploits distributed multistatic sensing to recursively track a mobile eavesdropper and quantify the associated position uncertainty. Since robu...

Pseudo-Noise Superposition for Finite-Alphabet Physical Layer Security

Physical-layer security based on pseudo-noise PN superposition is a promising approach for mitigating eavesdropping in future wireless systems. However, under Shannon's capacity formulation with Gaussian signaling, achieving secrecy typically requires allocating substantial transmit power to PN,...

JLSEC-2026-802 TLS 1.2 session resumption can renew one master secret indefinitely

Reseau 1.1.0 through 1.3.1 issue a fresh TLS 1.2 session ticket after a resumed handshake by copying the original master secret while resetting the ticket's creation and expiry times. A client that resumes at least once during every ticket lifetime can keep the same master secret valid...

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...

Investigation of STEEP for Secure Communications over SIMO and MISO Channels Subject to Full-Duplex Jamming and Eavesdropping

Secure communications over SIMO and MISO channels between wireless nodes are commonly encountered in applications and widely considered in the literature. This paper investigates such a problem by considering a newly proposed scheme called secrecy-message transmission by echoing encrypted probes...

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...

Quantum Secure Blind Decryption with Two Users

We propose two types of protocols for quantum secure blind decryption, involving two users and servers. User 1 holds the encrypted ciphertext. The servers store several indexed keys including the key encrypting the ciphertext. User 2 aims to obtain the decrypted text. The protocols are designed t...

Security-Aware Planning and Control of Multi-Agent Systems with LTL Tasks

This paper presents a secure-by-construction planning and control framework for multi-agent systems subject to linear temporal logic LTL specifications. The framework protects sensitive information from a passive intruder with partial observations of the agents' motion. Security in multi-agent...

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...

Joint Secrecy and Covert Communication (JSACC): An Enhanced Physical Layer Security Approach

In this paper, we propose an enhanced physical layer security approach, named joint secrecy and covert communication JSACC, which aims to improve the performance of physical layer security PLS. The JSACC system can dynamically switch between secrecy mode and covert mode according to the channel...

FoSAM: Forward Secret Messaging in Ad-Hoc Networks

Apps such as Firechat and Bridgefy have been used during recent protests in Hong Kong and Iran, as they allow communication over ad-hoc wireless networks even when internet access is restricted. However, these apps do not provide sufficient protection as they do not achieve forward secrecy in...

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...
