ELECTROMAGNETIC INFORMATION LEAKAGE EVALUATION SYSTEM AND METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To implement a compact and lightweight signal acquisition apparatus, and to quantitatively evaluate the risk of information leakage from an electronic device due to electromagnetic screen peep.SOLUTION: An electromagnetic information leakage evaluation system includes: a signal acquisition apparatus having means of receiving a leakage electromagnetic wave from an electronic device to be evaluated, and means of detecting the received leakage electromagnetic wave and converting it into a digital signal; a digital signal processing section which reconfigures a screen displayed on the electronic device, on the basis of the received leakage electromagnetic wave; and a display section for displaying the reconfigured screen. A correlation function between a reference screen acquired in advance and the reconfigured screen is calculated, and is compared with a threshold of a preset correlation coefficient, to evaluate the risk of electromagnetic screen peep of the electronic device.SELECTED DRAWING: Figure 1
