Meta-Learning-Driven GFlowNets for 3D Directional Modulation in Mobile Wireless Systems
Zhihao Tao, Athina P. Petropulu
In our prior work we have proposed the use of GFlowNets, a generative AI (GenAI) framework, for designing a secure communication system comprising a time-modulated intelligent refl…
Time-Modulated Intelligent Reflecting Surfaces for Integrated Sensing, Communication and Security: A Generative AI Design Framework
Zhihao Tao, Athina Petropulu, H. Vincent Poor
We propose a novel approach to achieve physical layer security for integrated sensing and communication (ISAC) systems operating in the presence of targets that may be eavesdropper…
Secure Time-Modulated Intelligent Reflecting Surface via Generative Flow Networks
Zhihao Tao, Athina P. Petropulu
We propose a novel directional modulation (DM) design for OFDM transmitters aided by a time-modulated intelligent reflecting surface (TM-IRS). The TM-IRS is configured to preserve…
Antenna Selection for Enhancing Privacy in Radar-Based Vital Sign Monitoring Systems
Zhihao Tao, Athina P. Petropulu
Radar-based vital sign monitoring (VSM) systems have become valuable for non-contact health monitoring by detecting physiological activities, such as respiration and heartbeat, rem…
On the Security of Directional Modulation via Time Modulated Arrays Using OFDM Waveforms
Zhihao Tao, Athina Petropulu
Time-modulated arrays (TMAs) transmitting information bearing orthogonal frequency division multiplexing (OFDM) signals can achieve directional modulation. By turning its antennas…
Enhance Security of Time-Modulated Array-Enabled Directional Modulation by Introducing Symbol Ambiguity
Zhihao Tao, Zhaoyi Xu, Athina Petropulu
In this paper, if the time-modulated array (TMA)-enabled directional modulation (DM) communication system can be cracked is investigated and the answer is YES! We first demonstrate…
