POWER-SUPPLaY: Leaking Data from Air-Gapped Systems by Turning the Power-Supplies Into Speakers [PDF]
, 2020 It is known that attackers can exfiltrate data from air-gapped computers through their speakers via sonic and ultrasonic waves. To eliminate the threat of such acoustic covert channels in sensitive systems, audio hardware can be disabled and the use of ...

Covert communication in relay and RIS networks
Security and Safety, 2023 Covert communication aims to prevent the warden from detecting the presence of communications, i.e. with a negligible detection probability. When the distance between the transmitter and the legitimate receiver is large, large transmission power is ...

BitWhisper: Covert Signaling Channel between Air-Gapped Computers using Thermal Manipulations
, 2015 It has been assumed that the physical separation (air-gap) of computers provides a reliable level of security, such that should two adjacent computers become compromised, the covert exchange of data between them would be impossible.

Enhancing Covert Secrecy Rate in a Zero-Forcing UAV Jammer-Assisted Covert Communication
IEEE Wireless Communications LettersCovert communications can hide confidential signals in environmental noise to avoid being detected and provide comprehensive security for wireless transmissions. However, there still exist significant risks in wireless transmission once being detected.

No Advantage for Separating Overt and Covert Attention in Visual Search
Vision, 2020 We move our eyes roughly three times every second while searching complex scenes, but covert attention helps to guide where we allocate those overt fixations.
