Are the humble analogue transducers embedded in vast numbers of sensors the next low-level technology in need of a security rethink?
A new research note discussing what are termed “transduction attacks” argues that they are being taken for granted but shouldn’t be.
To simplify, transducers are electronic components that turn analogue signals such as radio, sound or light waves, or the physical movement of something like a gyroscope, into an electrical signal that can be digitised by a computer.
