METHOD, SYSTEM AND DEVICE FOR CRYPTOGRAPHIC PROTECTION OF COMMUNICATION CHANNELS OF UNMANNED AERIAL SYSTEMS Russian patent published in 2019 - IPC H04L9/08 H04W12/06 

FIELD: cryptography.

SUBSTANCE: group of inventions relates to secure wireless communication systems and is intended to protect wireless communication channels between an unmanned aerial vehicle (UAV) or similar remotely controlled apparatus and a ground control station (GCS). Technical result is achieved using key carriers equipped with cryptographic functions, UAV and GCS mutual authentication scheme based on asymmetric cryptographic keys combined with common symmetric key calculation circuit, and a circuit for generating a session master key and encryption keys and calculating an simulator for subsequent generation of a secure wireless communication channel between the UAV and the GCS, which enables encryption of the transmitted information and monitoring its integrity, wherein the mutual authentication schemes, the common symmetric key calculations and the session keys generation are developed taking into account the UAV application specifics and the wireless communication channels formation between the UAV and the GCS.

EFFECT: provision of cryptographic protection of control channels, telemetry and data transfer of UAV payload from unauthorized access to data transmitted via data channels and its unauthorized modification.
