Covert Channel Between the CPU and An FPGA By Modulating The Usage of the Power Distribution Network
use Time-to-Digital Converter sensors to observe these power variations. The sensor circuits are programmed into the FPGA fabric using only standard logic components. Our covert channel achieves a ...
A new technical paper titled “Clock-to-Clock Modulation Covert Channel” was published by researchers at University of Rennes-INSA Rennes-IETR-UMR and University of South Brittany/Lab-STICC- UMR CNRS. ...
A new data exfiltration technique has been discovered, which uses a covert ultrasonic channel to leak sensitive information from air-gapped computers to a nearby smartphone device. The adversarial ...
