Acoustic cryptanalysis is a In cryptography, a side channel attack is any attack based on information gained from the physical implementation of a cryptosystem, rather than weaknesses in the mathematical algorithms (compare cryptanalysis). For example, timing information, power consumption or even sound provide an extra channel of information, which can be exploited to break... side channel attack which exploits This article is about compression waves.
