= Acoustic cryptanalysis
{wiki=Acoustic_cryptanalysis}
Acoustic cryptanalysis is a technique used to extract cryptographic keys from devices by analyzing the sounds they make during operations. This method capitalizes on the acoustic emissions that result from electronic device activities, such as key presses on a keyboard or the operations of a computer's processor. The basic premise of acoustic cryptanalysis is that when a device performs cryptographic operations, it may generate subtle sounds that can reveal information about the keys being used.
