The problem of the description of artificially present industrial noises which are available at operation of personal computers is considered in work. These noises have both positive and negative effects when protecting the information typed by the user by means of the USB keyboard interface. The difficulties that arise in this case are due to the fact that the indirect radiation of electromagnetic fields is observed during the operation of all elements of computer technology. On the one hand, the presence of these noises distorts the useful signal, which in turn prevents the attacker from detecting reliable information that is transmitted. On the other hand, these noises prevent the creation of appropriate measures to ensure complete protection when typing by a user of a personal computer. The paper proposes to consider industrial noise in the form of three random processes, which are described by Johnson distributions.
