FIELD: radio engineering and communication.
SUBSTANCE: invention relates to means of secret transmission of messages using a plurality of noise-like signals (NLS). Method consists in transmission of message elements by one of NLS ensemble. System comprises a converter of input discrete messages, a unit of switches, a NLS generator, a control unit, a communication channel, a matched filter, a resolver, code encryption key generator, message element restorer, decoder, decryption key generator.
EFFECT: higher security of message transmission owing to encryption of the NLS number, providing energy-secret transmission of messages to a user over a communication channel in the presence of noise and interference.
