Noise Resilience of Quantum Key Distribution Protocols Secured against Independent Attacks with One-Way Communication

We investigate the resilience to noise of single-qubit quantum key distribution QKD protocols in the scenario of security against independent eavesdropping attacks and key distillation based on one-way classical communication. To this end, we introduce a noise-based metric that quantifies the...

Hacking Measurement-Device-Independent Quantum Key Distribution

The security of practical quantum key distribution QKD systems is fundamentally constrained by vulnerabilities of single-photon detectors. Measurement-device-independent quantum key distribution MDI-QKD was proposed to remove this limitation by allowing all measurements to be performed by a...

PRoADS: Provably Secure and Robust Audio Diffusion Steganography with Latent Optimization and Backward Euler Inversion

This paper proposes PRoADS, a provably secure and robust audio steganographic framework based on audio diffusion models. As a generative steganography scheme, PRoADS embeds secret messages into the initial noise of diffusion models via orthogonal matrix projection. To address the reconstruction...

MALRIS: Malicious Hardware in RIS-Assisted Wireless Communications

Reconfigurable intelligent surfaces RIS enhance wireless communication by dynamically shaping the propagation environment, but their integration introduces hardware-level security risks. This paper presents the concept of Malicious RIS MALRIS, where compromised components behave adversarially, ev...

Performance Analysis of MDI-QKD in Thermal-Loss and Phase Noise Channels

Measurement-device-independent quantum key distribution MDI-QKD, enhances quantum cryptography by mitigating detector-side vulnerabilities. This study analyzes MDI-QKD performance in thermal-loss and phase noise channels, modeled as depolarizing and dephasing channels to capture thermal and phase...
