Contribution

It provides the first extensive survey of acoustic side channels, discusses security implications, and bridges them with inverse problem research.

Findings

Comprehensive analysis of acoustic side channels and their security implications

Identification of countermeasures for acoustic side channels

Bridging acoustic side channels with inverse problem research

Abstract

We provide a state-of-the-art analysis of acoustic side channels, cover all the significant academic research in the area, discuss their security implications and countermeasures, and identify areas for future research. We also make an attempt to bridge side channels and inverse problems, two fields that appear to be completely isolated from each other but have deep connections.
