Özet:

 

Each electronic (electric) device generates   electromagnetic emissions during its operation. Most often these emissions   are generated unintentionally and they are radiated into the surrounding   space in an uncontrolled way. In the case of significant levels of these   emissions, they can disturb the operation of other devices or can be used as   typical radio emissions. If the nature of their changes corresponds to the   processed information occurring in a form of electric signals, the mentioned   emissions can be a basis for effective realization of electromagnetic   infiltration processes. Most often, these emissions are classified in   laboratory conditions using anechoic chambers. Inside such chambers there   are not additional sources of emissions that would increase the level of   electromagnetic protection through disturbance of sensitive emissions. The   sensitive emissions have distinctive features corresponding to the processed   information. Using these emissions, the reconstruction of primary   information is possible. This article presents the results of tests of a   laser printer with a two-diode laser system, operated in an open space and   in office rooms, outside the anechoic chamber. These are so-called real   conditions of operation of the device. The purpose of the tests was to show   the existence of risks in a typical electromagnetic environment. Additional   sources of emissions or occurring obstacles, e.g., walls of offices, do not   reduce levels of sensitive emissions to safe values. The electromagnetic   infiltration process is possible in each of the mentioned environments and   its effects are presented in the form of reconstructed images. The distances   on which the compromising emissions are measured deserve special attention.   They are equal to even several meters.
