This paper examines the possibility, performance limits, and associated costs for a self-
sustained relay to transmit its own covert information to a destination on top of forwarding the …

Covert wireless communication aims to hide the very existence of wireless transmissions in
order to guarantee a strong security in wireless networks. In this paper, we examine the …

In this paper, we investigate the feasibility and performance of the covert communication
with a spectrum sharing relay in the finite blocklength regime. Specifically, the relay …

Covert communication aims to shield the very existence of wireless transmissions in order to
guarantee a strong security in wireless networks. In this work, for the first time we examine …

In this letter, we investigate covert communication in relay networks with relay selection. We
consider the scenario that while forwarding the source's message, the selected relay …

We investigate covert wireless communication in a multi-antenna relay network, where the
relay transmits its own covert message to the destination when assisting the source's …

This work, for the first time, tackles channel estimation design with pilots in the context of
covert wireless communication. We consider Rayleigh fading for the communication channel …

Covert communications hide the transmission of a message from a watchful adversary while
ensuring a certain decoding performance at the receiver. In this paper, a wireless …

In this letter, we consider delay-constrained covert communications with the aid of a full-
duplex (FD) receiver. Without delay constraints, it has been shown that the transmit power of …

In this paper, we investigate the performance of covert communications in different types of a
relay system: decode-and-forward (DF), compress-and-forward (CF) and amplify-and …
