Abstract

Electromagnetic leakage will happen in working information equipments; it could lead to information leakage. In order to discover the nature of information in electromagnetic leakage, this paper combined electromagnetic theory with information theory as an innovative research method. It outlines a systematic model of electromagnetic information leakage, which theoretically describes the process of information leakage, intercept and reproduction based on electromagnetic radiation, and analyzes amount of leakage information with formulas. DOI : http://dx.doi.org/10.11591/telkomnika.v12i2.4010

Abstract

Computer and other digital electronic equipments can emit unintentional electromagnetic signals in the state of information processing. The compromising electromagnetic emanations allow eavesdroppers to reconstruct processed data at a distance that threatening the information security. As s result all equipments handling confidential information do need TEMPEST security testing. This paper attempts to design a mathematical model for TEMPEST testing that will facilitate the analysis of the key factors in TEMPEST testing and standard revising. DOI : http://dx.doi.org/10.11591/telkomnika.v12i2.4006
