FIELD: information technology.
SUBSTANCE: method of protecting computer equipment from information leakage through a compromising emanation channel and noise pick up involves generating a masking signal, wherein N files are created, whose content does not need protection; the first part of 0.5N files from the common list is recorded in a first digital medium, and a second part of 0.5N files from the common list is recorded in a second digital medium; further, a file randomly selected from the list is read from the first digital medium and then recorded in the second digital medium, while simultaneously reading a file randomly selected from the list from the second digital medium and recording said file in the first digital medium; recording and reading of files is carried out repeatedly over a time period required for masking the message-bearing signal.
EFFECT: easier technical implementation of protecting information in computer equipment from leakage through a compromising emanation channel and noise pickup.
