FIELD: information protection.
SUBSTANCE: method for increasing the reliability of information processing is disclosed, in which, during processing of information in the form of digital signals, an information processing path is supplemented with an additional processing path, and information is processed in the additional processing path simultaneously with information processing in the protected processing path, while processing in the additional processing path is carried out in the form of signals, amplitude and frequency-time parameters of which are selected in such a way that a picture of channels of side electromagnetic radiation and leads (hereinafter – SEMRL) of both paths in general, appearing in the surrounding space during information processing, is identical for each processing path, while, in completion of information processing in the protected processing path and in the additional information processing path, results of information processing in both processing paths are compared for compliance with each other; in case of compliance, a decision is made on reliable information processing, in case of incompliance, a decision is made on unreliable information processing.
EFFECT: increase in the reliability of information processing during its protection from leakage through SEMRL channels.
