METHOD OF CRYPTOGRAPHIC PROTECTION OF COMMUNICATION CHANNELS BETWEEN A GROUND CONTROL STATION AND SIMULTANEOUSLY SEVERAL UNMANNED AERIAL VEHICLES Russian patent published in 2020 - IPC H04L9/08 H04B7/26 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to secure wireless communication systems. Technical result is achieved due to non-repeating UAV private secret keys, generation on GCS common secret key of next communication session, transmitting on UAV calculated from common secret key non-secret augmented keys of regular session of communication, mutual authentication of UAV and GCS, coordinated formation of UAV and GCS encryption key and key calculation imitation, at which secure transmission of control, telemetry and payload information of the next communication session is provided, wherein control information is transmitted simultaneously to all UAV, and in case of arbitrary UAV number failure, the common secret key of the next communication session is generated again, the added keys are calculated and transmitted and the protected information transmission for GCS and the remaining UAV is restored.

EFFECT: technical result consists in provision of cryptographic protection of communication channels between ground control station and simultaneously several drone-controlled aircrafts without delay of transmission of control commands to UAV group.
