	Acoustic cryptanalysis
		When several computers are present, they can be told apart by their different acoustic signatures, since these vary with the hardware, the component temperatures, and other environmental conditions.
		Another acoustic source is hard disk head seeks; this source does not appear very useful in the presence of caching, delayed writes and multitasking.
		This computer was chosen for its particularly striking acoustic emanations, but is by no means a special case: every computer we tested showed significant correlation between acoustic spectrum and CPU activities, and in about half the cases the effect could be heard by naked ear when using appropriate CPU activity patterns.

	Acoustic cryptanalysis - Wikipedia, the free encyclopedia
		Acoustic cryptanalysis is a side channel attack which exploits sounds, audible or not, produced during a computation or input-output operation.
		Also in 2004, Adi Shamir and Eran Tromer demonstrated that it may be possible to conduct timing attacks against a CPU performing cryptographic operations by analysis of variations in its humming noise.

		The use of acoustic warfare support measures involves no intentional underwater acoustic emission and is generally not detectable by the enemy.
		That aspect of acoustic warfare involving actions taken to ensure friendly effective use of the underwater acoustic spectrum despite the enemy's use of underwater acoustic warfare.
		Acoustic warfare counter-countermeasures involve anti-acoustic warfare support measures and anti-acoustic warfare countermeasures, and may not involve underwater acoustic emissions.

	Bishop John Wilkins
		It is much more than that: it is a treatise on the state of the art in seventeenth century telegraphy.
		He explains how the letters of the alphabet can be represented as five bits each and then transmitted using any available means - such as two different bells, or a musket shot for `0' and a cannon shot for `1'.
		As well as showing how to break simple substitution ciphers, and introducing various geometrical enciphering schemes, he proposes the use of nulls to make cryptanalysis harder.

		This computer was chosen for its particularly striking acoustic emanations, but is by no means a special case: every computer we tested showed significant correlation between acoustic spectrum and CPU activities, and in about half the cases the effect could be heard by naked ear when using appropriate CPU activity patterns.
		Notably, its acoustic emanations are different (and less informative) when running on AC power supply.

	SecuriTeam™ - Acoustic Cryptanalysis: On Nosy People and Noisy Machines
		Adi Shamir and Eran Tromer published a research paper and Proof of Concept discussing an idea for a cryptanalysis technique that uses the noise emitted by a computer's CPU.
		Second, we get temporal information about the length of each operation, and this can be used to mount timing attacks, especially when the attacker can affect the input to the operation (i.e., in chosen-ciphertext attack scenario).
		Eavesdropping on keyboard keystrokes has been often discussed; keys can be distinguished by timing, or (as recently proposed by Asonov and Agrawal) by their different sounds.

		A powerful method for extracting information from supposedly secure systems is side-channel attacks: cryptanalytic techniques that rely on information unintentionally leaked by computing devices.
		Our prelimary analysis of acoustic emanations from personal computers shows them to be a surprisingly rich source of information on CPU activity.

		Side-channel cryptanalysis exploits physical information leakage from cryptographic devices to undermine their security.
		Most side-channel attacks require special measurement equipment and are thus limited in applicability.
		Second, acoustic emanations from electronic circuit components can be information-bearing and are often detectable by a plain microphone.

		New cryptanalysis techniques are being discovered constantly, but I doubt that NSA has any significant advantage in this field if compared to achievement of academic research community.
		Good example of such research is recent “Acoustic cryptanalysis – preliminary proof of concept” by Shamir and Tromer (see
		But other than that – the only reliable way of breaking standard proven encryption algorithms is brute force key search attack, and that is where current hardware limits are actually the same hinder for NSA as for all us mortals.
