STAR-RIS Aided Covert Communications

GLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023
This paper investigates the multi-antenna covert communications assisted by a simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS). In particular, to shelter the existence of communications between transmitter and receiver from a warden, a friendly full-duplex receiver with two antennas is leveraged to make ...

Acoustic projectors make covert bioacoustic chirplet signals discoverable

Scientific Reports, 2023
To disguise man-made communications as natural signals, underwater transceivers have the option to pre-record animal vocalizations, and play them back in a way that carries meaningful information for a trained receiver.

Inaudible sound covert channel with anti-jamming capability: Attacks vs. countermeasure

Journal of Electronic Science and Technology, 2022
When an inaudible sound covert channel (ISCC) attack is launched inside a computer system, sensitive data are converted to inaudible sound waves and then transmitted.

Delay Normalization Technique to Disrupt Covert Timing Channels Using Active Warden [PDF]

EPJ Web of Conferences
Covert channels exploit existing network resources, such as packet headers and timing information, to transfer information in ways not originally intended for communication, making them undetectable by conventional methods.

Covert Communication in Fading Channels under Channel Uncertainty [PDF]

, 2017
A covert communication system under block fading channels is considered where users experience uncertainty about their channel knowledge. The transmitter seeks to hide the covert communication to a private user by exploiting a legitimate public ...
