Specialists from the Krasnodar Higher Military School named after General S.M. Shtemenko have developed a method for imitation protection of information transmitted in a packet radio network of a group of unmanned aerial vehicles, according to a publication in the Rospatent database. The invention is aimed at increasing data security against forgery and unauthorized access.
The essence of the method lies in multi-level verification. First, the system calculates the boundaries of spatial zones based on the limiting parameters of the physical interaction of UAV radio equipment. Then, an individual secret key for generating an imitation insert, a signature key, and an array of signature verification keys for devices within physical reach are written into the memory of each drone.
When transmitting data, the receiving side controls the signal at the physical level — evaluating the signal power level at the receiver input to determine if the drone belongs to the authorized zone. At the channel level, the electronic signature is verified using the signature verification key, and the value of the imitation insert is calculated to confirm the authenticity of the message.
The technical result achieved by the developers is an increase in the imitation protection of information transmitted in the radio network of a UAV group. The patent has already been obtained. The development can be applied in military and civilian communication systems using unmanned aerial vehicles, where protection against data spoofing and control interception is required.
