RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis

“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. (…)

A detailed accounts of the results and their context is given in the full version of our paper (8MB PDF).
