Abstract

TEMPEST Font Protects Text Data against RF Electromagnetic Attack

Highlights

  • Protection of information against electromagnetic penetration process is a very important challenge

  • The font does not possess distinctive features. This phenomenon causes that at an output of Side Channel Attack the possibilities of recognition of each character which appears on the reconstructed image for sources in the form of graphic lines (VGA and DVI) are limited

  • TEMPEST font was devoid of distinctive features in contrast to traditional fonts (Arial and Times New Roman)

Summary

INTRODUCTION

Protection of information against electromagnetic penetration process is a very important challenge. The most spectacular phenomenon consists in the opportunity of displaying acquired data in a form that is comprehensible for a person This in particular concerns sources of emissions in the shape of graphic lines, e.g. VGA or DVI standards [7,8,9,10,11,12] and laser systems of typical laser printers [13,14,15,16]. Because the non-invasive data acquisition is very dangerous, the sources of electromagnetic emissions correlated with processed graphic information are the subject of analyses and tests. The filtering of video signal is not a solution which could be applied to different graphic sources of sensitive emissions It is effective in case of analog standard. New idea is effective for different graphic sources of sensitive emissions, e.g. DVI and VGA video standards, different types of laser printers [16]
