CE components, the secondary radiation is modulated by an informative signal. The
“reradiated” secondary signal is received by the receiver of the intelligence equipment
and detected.
Also, to intercept CE-processed information, special electronic information interception devices can be used—hardware Trojans, secretly introduced in the equipment
and systems (Fig. 1.23) [1].
The information intercepted using hardware Trojans is either directly transmitted
via a communication channel to the point of reception or is recorded on a special
storage device and transmitted only by a control command.
To transmit information to the receiving point, a radio channel, an optical (infrared)
channel, and even a CE electrical power line can be used (Fig. 1.18).
