Researchers Hack RSA with Acoustic Cryptanalysis

From CS.tau.ac:
Many computers emit a high-pitched noise during operation, due to vibration in some of their electronic components. These acoustic emanations are more than a nuisance: they can convey information about the software running on the computer and, in particular, leak sensitive information about security-related computations. In a preliminary presentation, we have shown that different RSA keys induce different sound patterns, but it was not clear how to extract individual key bits. The main problem was the very low bandwidth of the acoustic side channel (under 20 kHz using common microphones, and a few hundred kHz using ultrasound microphones), many orders of magnitude below the GHz-scale clock rates of the attacked computers.

Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA. The attack can extract full 4096-bit RSA decryption keys from laptop computers (of various models), within an hour, using the sound generated by the computer during the decryption of some chosen ciphertexts . . .

  3. I read your post when it was fresh. I stumbled on this link again while searching for something else. Since this appears to be favored by Google it is worth pointing out MS has changed its mind.

    HP is a world-renowned computer and software company headquartered in the United States. With annual revenues of $53 billion, it is considered as the first choice in the field.
    According to analysis, due to the fraudulent means of our competitors, candidates hesitate to buy HP Q&A PDF files. If the Killer Dumps allows them to get their money back even after preparing the HP Certification exam, this service received a very positive response. So be smart and buy our updated HP Exam Dumps 2019 and save you time and money.
