Abstract

The development of microelectronics forms new channels of confidential information leakage. The transmission of acoustic information by digitally modulating the light output of LEDs has now become physically realizable. Theoretical calculations showed a high potential sensitivity of MEMS microphones. The combined use of digital MEMS microphones and LED room lighting controllers allows you to transmit a digital data stream of 40 800 Bits / s over 100 meters with minimal signal-to-noise ratios. Conducted research reveals a new information leakage channel and describes its characteristics, which will make it possible to develop administrative and technical
countermeasures.
