FIELD: radio engineering, communication.
SUBSTANCE: method involves generating a masking broadband noise signal using two noise signals with frequency spectrum division and subsequent summation of signals on the electromagnetic field by mixing the broadband noise signal with the clock signal of an information processing system. The apparatus includes a source of a low-frequency noise signal, a source of a high-frequency noise signal, a clock frequency unit of the information processing system, a mixer for mixing the noise signal and the clock frequency signal and an amplifier.
EFFECT: high protection of processed information, high entropy quality factor of noise, wide frequency spectrum of the noise signal in both the low-frequency and high-frequency regions.
