Acoustic Cryptanalysis

Definitions

1. A side-channel attack technique that derives secrets by analyzing sound produced during cryptographic operations or device behavior. It relies on unintended physical leakage rather than breaking the math directly.

   In plain English: Trying to break secrets by listening to sounds a device makes while doing crypto work.

   Example: "The lab demonstrated acoustic cryptanalysis by recovering key material from hardware emitting subtle coil-whine patterns."
