An automatic control (recovery) system for reception of USB-Keyboard Compromising Emanations has been developed. The synthesized system consists of three interconnected parts: a record unit, an optimal recovery unit, and a sensitive extraction unit. The system has been implemented as a digital model in the LabView software. The digital experiment on estimation of sync system efficiency under the Johnson noise conditions has been carried out when recovering the informative USB-keyboard compromising emanation with data on button pressing. The efficiency is compared with existing system of signal detection by the CCF maximum value at the correlator output.
