Multicast with Multiple Wardens in IRS-Aided Covert DFRC System

Indrasish Ghosh, Arpan Chattopadhyay, Kumar Vijay Mishra, Athina P. Petropulu

ICASSP 2024accepted

Physical layer security is a common concern in dual-function radar communications (DFRC) because of sharing of information between different emitters. We study covert communications between a DFRC unit and multiple legitimate users, with assistance from an intelligent reflecting surface (IRS). The s…

Optm3sec: Optimizing Multicast Irs-Aided Multiantenna Dfrc Secrecy Channel With Multiple Eavesdroppers

Kumar Vijay Mishra, Arpan Chattopadhyay, Siddharth Sankar Acharjee, Athina P. Petropulu

ICASSP 2022accepted

With the use of common signaling methods for dual-function radar-communications (DFRC) systems, the susceptibility of eavesdropping on messages aimed at legitimate users has worsened. For DFRC systems, the radar target may act as an eavesdropper (ED) that receives a high-energy signal thereby leadin…
