METHOD FOR INCREASING SECURITY OF DATA TRANSMISSION AND RADIO COMMUNICATION SYSTEM WITH INCREASED SECURITY PROTECTION Russian patent published in 2023 - IPC H04L9/00 H04K3/00 

FIELD: radio engineering.

SUBSTANCE: invention can be used in secure radio communication systems. To achieve the effect, the system includes multi-channel broadband radio stations with code division of channels and uses a mixed method of spreading the spectrum based on pseudo-random tuning of the operating frequency with pre-expansion of the spectrum using the direct sequence method. The entire frequency range is covered by wideband signals from each channel of the radio station, while the overlay of dedicated bands and pseudo-random hopping of the operating frequency between channels is applied. When the transmission of information on certain channels or the entire radio station as a whole is stopped, false information messages are transmitted on the air in order to hide the fact of termination of work and create additional interference with the radio communication systems of the opposing side.

EFFECT: increasing the security of communication channels and security of data transmission.
