Generalized Analysis Model of Information Security of Computer System Based on Electromagnetic Topology

According to the character of the typical serial information leakage and the feature in the information leakage problem that multiple points (zone) converge and couple toward one point (zone), several key concepts, such as the emission zone, transmission zone and receiving zone, are defined in this paper. Based on the idea of electromagnetic topology, a completely new construction method of system topological graph is proposed. Then, this method is applied to analyze a simplified serial information leakage system, the generalized transmission coupling model is also established. What´s more, the modeling process of field-to-field coupling is discussed emphatically. Therefore a solid foundation is laid for the electromagnetic topology analysis of serial information leakage.
