Abstract

The display image of a PC can be reconstructed by using the conducted emission on the PC's network cable. The relevant signals which be used to reconstruct the original image are partly contained in the frequency region higher than 30MHz in the conducted emission. Illegal authorizer can reconstruct the original display image on the other place of the LAN without being noticed. Firstly, a transmission model for the video signals which transmit in the network cable is proposed. And then, the maximum safe distance is estimated by using this model. Lastly, in order to check the validity of the estimating distance, the eavesdropping experiment is carried out to reconstruct the original display image.
