Analysis of Information Leakages on Laser Printers in the Media of Electromagnetic Radiation and Line Conductions
Abstract
In this paper, the emissions of a laser printer, which may process classified information, are investigated in the media of electromagnetic radiation (ER), Power Line Conductors (PLC), and Signal Line Conductors (SLC). First, the candidate frequency points of CE are examined in the frequency domain. Second, the emitted signal is AM-demodulated with the proper bandwidth, and then sampled by a high storage oscilloscope in these frequency points. Third, the collected data is converted to 2D image by applying signal and image processing techniques. In addition, this study introduces some practical measurement methods to reveal the possible CEs of laser printers. Finally, the procedure of the image reconstruction of CEs of the laser printer data is explained in detail.
