Secure Integrated Sensing and Communications with Movable Beyond-Diagonal RIS
In integrated sensing and communication ISAC, when the sensed target is itself an eavesdropper, the illumination required for sensing coincides with the leakage that secrecy must suppress. This paper shows how a beyond-diagonal reconfigurable intelligent surface BD-RIS with movable elements...
Generative Diffusion Models for Secure UAV-ISAC with Real-Time Target Tracking
Unmanned aerial vehicle UAV platforms with integrated sensing and communication ISAC are prime candidates for surveillance missions, in which a dual-function drone tracks a mobile target and alerts a ground station when the target enters a protected region. Such alerts generate event-triggered...
Sensing-Driven Secure Transmission with Mobile Eavesdropper Tracking in RIS-Assisted ISAC
The mobility of potential eavesdroppers Eves poses a critical challenge to physical-layer security PLS in integrated sensing and communication ISAC systems, since rapidly varying Eve positions lead to time-varying eavesdropping channels and outdated security decisions. To address this challenge,...
Robust Design of Sensing-Assisted Secure Transmission for RIS-Aided ISAC System under Eavesdropper 3D Positioning Uncertainty
Localization errors in estimating the position of a potential eavesdropper Eve pose a critical challenge to secure transmission in reconfigurable intelligent surface RIS-assisted integrated sensing and communication ISAC systems. To address this issue, this paper proposes a sensing-assisted robus...
Simultaneous Secure Communications and Sensing Privacy with Full Duplex MIMO Radios
This paper proposes a Full Duplex FD framework for safeguarding Integrated Sensing and Communications ISAC against a passive multi-antenna Eavesdropper Eve. The adversary is modeled as both a communication and sensing threat, seeking to decode uplink data streams and estimate the surrounding scen...
Waveform Randomization for Secure ISAC
This paper studies waveform-level security for Integrated Sensing and Communication ISAC. Instead of relying on spatial beamforming or power allocation, we randomize the sensing waveform itself using phase keys and tangent Artificial Noise AN applied to a Fourier-curve constellation. Coordinated...
An Operational Leakage Metric for Eavesdropping in Joint Sensing and Communications Systems
In upcoming integrated sensing and communications ISAC systems, security depends on whether an eavesdropper Eve can recover data symbols or infer sensing information from a common observation with a legitimate receiver. However, existing information and estimation measures do not quantify this du...
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...
Securing Cooperative Sensing in UAV Swarms against Conformity-Driven Byzantine Attacks
In integrated sensing and communication ISAC enabled 6G unmanned aerial vehicle UAV swarm networks, the widely adopted imitation-based conformity cooperation mechanism can be exploited by Byzantine attackers to fabricate false consensus, causing the effective error probability of normal UAVs to...
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...
