Abstract

This paper presents a new approach to the TEMPEST compromising signals emitted by the printing devices. From the TEMPEST point of view, only the laser printer diodes and the printer-computer communication signals have been considered as compromising signal generators so far. In this paper we will present some examples of video signal recovery from the compromising signal generated by the laser printer LCD display as well as a number of measurement results of the video signal parameters for particular video display signals which have been selected for this reason.
