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...
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...
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,...
Communication Security Via Temporal Dependency
Communication security has traditionally been built upon one of two external resources: shared secret keys or a communication advantage over the eavesdropper. However, many practical wireless scenarios, including infrastructure-less, emergency, and highly dynamic networks, cannot guarantee either...
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...
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...
Pattern Based Quantum Key Distribution Using the Five Qubit Perfect Code for Eavesdropper Detection
I propose a new quantum key distribution protocol that uses the five qubit error correction code to detect the presence of eavesdropper reliably. The protocol turns any information theoretical attacks into a classical guess about the pattern. The logical qubit is encoded with a specific pattern...
CKM-Assisted Physical-Layer Security for Resilience against Unknown Eavesdropping Location
Channel Knowledge Map CKM is an emerging data-driven toolbox that captures our awareness of the wireless channel and enables efficient communication and resource allocation beyond the state of the art. In this work, we consider CKM for improving physical-layer security PLS in the presence of a...
CVE-2022-47930
An issue was discovered in IO FinNet tss-lib before 2.0.0. The parameter ssid for defining a session id is not used through the MPC implementation, which makes replaying and spoofing of messages easier. In particular, the Schnorr proof of knowledge implemented in sch.go does not utilize a session...
CBL Mariner 2.0 Security Update: postgresql (CVE-2024-4317)
The version of postgresql installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-4317 advisory. - Missing authorization in PostgreSQL built-in views pgstatsext and pgstatsextexprs allows an unprivileged...
