On the possibility of analytical detection of the TEMPEST signal in HDMI video interfaces



This paper presents the theory and the practical proof of the possibility of detecting the TEMPEST signal in digital video interfaces. A comparative analysis of the possibility of ob­tai­ning information from VGA and HDMI video interfaces by means of TEMPEST was car­ried out. In accordance with the results of the analysis, a theoretical assumption was put for­ward and practically proved later.
