Research on Computer Radiation Security
In view of the electromagnetic information leakage of information security implication, the time-frequency characteristics of radiation signal from LCD display with a resolution of 1280×1024 through simulation is analyzed in this paper. The design and measurement of the shielding box is given. A USA military standard testing is made, which shows that the designed shielding box is less than the overall emission of radiation 35 dBμV/m and with a proper increase In protection radius, the amount of its radiation emission can be reduced to 20 dBμV/m or less, lower than the 20 dBμV/m of the ambient noise thus meeting the information security requirements.
