FIELD: radio engineering.
SUBSTANCE: invention relates to the field of radio engineering, computer equipment and systems of noise-resistant covert transmission of encrypted discrete messages in the presence of noise using a finite set of noise-like signals (NLS). The method consists in transmitting each element of the message by one of the NLS of the ensemble. The system contains an encoder, a decoder, a trigger signal generator, an NLS generator, a communication channel, a matched filter, a resolver, a discrete message restorer, encryption and decryption key generators.
EFFECT: increasing the security of discrete messages, ensuring the energetically secretive transmission of encrypted discrete messages to the user in an optimal way, including in the presence of noise.
