FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering, computer equipment and systems for noise-immune covert transmission of encrypted discrete messages. Method consists in transmitting each message unit by one of the noise-like signals within the boundaries of the variable time slot. System comprises an encoder, a decoder, a trigger signal generator, a generator, communication channels, a matched filter, a resolver, a recovery device of discrete messages, generators of encryption and decryption keys, a slot programmer.
EFFECT: high security of discrete messages due to encryption, providing energy-secret transmission of encrypted discrete messages to a user over a communication channel, including in the presence of noise.
