Benefits of coherent demodulation for eavesdropping on HDMI emissions
Friday, 30 August, 2024 - 14:00 to 14:30
Demonstrations of electromagnetic eavesdropping attacks on digital video-interface cables usually first amplitude-demodulate the received signal, then resample the result into pixel-aligned raster images, and finally average consecutive video frames obtained this way. This non-coherent process discards useful phase...
