Risk Reducing of Information Leakage Due to Compromising Emanation A. N. Anishchenko, A. V. Lyashenko, P. A. Solopov, L. S. Sotov

The results of wide band electromagnetic emission produced by computer are ex-plained. The measurements are done from 20 MHz to 1000 MHz. We found out what parts produce maximum emission, and suggest а method to minimize risk of leakage from uninten-tional electromagnetic emanations produced by computer on personal work place. It is shown that good practice is to fast encrypt of data transmitting by long wires.
