FIELD: information technologies.
SUBSTANCE: method consists in generation of a noise signal and its mixing with an additional signal with subsequent use of a signal produced as a result of mixing as a masking signal, an additional signal is a clock signal of the information processing system (IPS). The device comprises a noise signal generator, an amplifier, a signal frequency converter, such as a unit of the information processing system clock frequency, and a signal frequency converter is a mixer of a noise signal and a signal of the information processing system clock frequency.
EFFECT: reduced capacity of a masking noise signal with coverage of radiation level and frequency spectrum.
