New side-channel attack leverages coil whine
Jun 4, 2016 21:44 GMT · By Catalin Cimpanu Sound emanating from different components exchanging data inside a computer can leak cryptographic keys, a team of five researchers from the University of Tel Aviv has discovered.
The researchers exploited coil noise, also known as coil whine, a term used to describe the sound made by coils and other components as electrical current passes through them.
The team of five says they can measure this sound and extract binary operations from the soundwaves. By knowing the exact pattern of bits, they can reverse engineer computer operations.
