ACOUSTIC CRYPTANALYSIS

SEMINAR ON ACOUSTIC CRYPTANALYSIS : Acoustic cryptanalysis is an attack that exploits the semi-channel sound, audible or not, are produced in the computation or input-output function. In 2004 Dmitri Asonov and Rakesh Agrawal IBM Almaden Research Center has announced that computer keyboards and keypads used for telephones and automated teller machines (ATMs) are vulnerable to attacks based on the distinction between the sound produced by different keys. Their attack employed by the neural network to identify the key pressed. By analyzing recorded sounds, they were able to retrieve data from text. These technologies allow an attacker to use covert listening devices to obtain password, passphrase, personal identification numbers (PIN) and information security. Also in 2004, Adi Shamir and Eran Tromer shown that it may be possible to carry out attacks on the timing of the CPU to perform cryptographic operations, analyzing the fluctuations of the humming.
In his book Spycatcher, Peter Wright, MI5 patch age relates to the use of an attack against Egypt acoustic Hagelin cipher machines in 1956. The attack is called "swallow."
