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...
