Analysis of Compromising Emanations from a Laser Printer Printing Head for the Purpose of Assess the Possibility of Information Interception

Abstract

This article shows how to calculate and extract the desired harmonic of compromising informative signal from a laser printer printing head. There are the formulas for determining the frequency of the testing compromising informative signal for extracting of it in the particular frequency range. Also it shows in detail the process of radio scanning and authenticating compromising informative signal from a laser printer printing head.
