METHOD FOR HIDDEN SECURE TRANSMISSION OF TELEMETRY DATA IN ROBOTIC COMPLEXES Russian patent published in 2022 - IPC H04L9/00 G06F11/08 H04N7/08 

FIELD: communication.

SUBSTANCE: invention relates to telemetry, communication equipment, and can be used in systems for transmitting telemetry data in robotic complexes. The secret key K_steg is exchanged between the correspondents. The digitised telemetry data s₁, s₂, …, s_l are grouped into i=l/k telemetry frames … , encoded with an interference-resistant multivalued (n, k) code, forming code patterns C₁=(c_1,1 c_1,2, …, c_1,k+r) C₂=(c_2,1c_2,2, …, c_2,k+r), C_i=(c_i,1, c_i,2, …, c_i,k+r). The procedure of interleaving the characters of code patterns is performed forming new character sequences. Based on the key K_steg, the sequences C₁, C₂, …, C_k+r are integrated into the multimedia data transmitted by the robotic complex by steganography methods. On the receiving side, the elements of sequences are extracted from the multimedia data based on the key K_steg, the procedure of de-interleaving the characters is performed forming code patterns, the stage of interference-resistant decoding thereof is executed.

EFFECT: ensured secrecy of the fact of transmission of telemetric data.
