Quantum Advantage in Multiple Access Wiretap Channels with Entangled Transmitters

Hassan ZivariFard, Xiaodong Wang

We investigate secure communication over a classical multiple-access wiretap channel (MAC-WTC), specifically exploring the benefit of shared entanglement between the transmitters.…

Keyless Covert Communication Over Quantum MACs with General Message Sets

Hassan ZivariFard, Xiaodong Wang

We study covert classical communication over quantum multiple-access channels (MACs) with general message sets. Specifically, we consider a fully quantum MAC with arbitrary message…

Covert Communication and Key Generation Over Quantum State-Dependent Channels

Hassan ZivariFard, Rémi A. Chou, Xiaodong Wang

We study covert communication and covert secret key generation with positive rates over quantum state-dependent channels. Specifically, we consider fully quantum state-dependent ch…

Resource Allocation for Positive-Rate Covert Communications Using Optimization and Deep Reinforcement Learning

Yubo Zhang, Hassan ZivariFard, Xiaodong Wang

We aim to achieve keyless covert communication with a positive-rate in Rayleigh block-fading channels. Specifically, the transmitter and the legitimate receiver are assumed to have…

Covert Communication Over a Quantum MAC with a Helper

Hassan ZivariFard, Rémi A. Chou, Xiaodong Wang

We study covert classical communication over a quantum multiple-access channel (MAC) with a helper. Specifically, we consider three transmitters, where one transmitter helps the ot…

Covert Communication via Action-Dependent States

Hassan ZivariFard, Xiaodong Wang

This paper studies covert communication over channels with ADSI when the state is available either non-causally or causally at the transmitter. Covert communication refers to relia…
