Hardware-software complex protection of telemetry and telecontrol of specialized unmanned aerial vehicles

This article discusses the problem of creating a secure communication channel with specialized UAV. This problem is very relevant today, because an unprotected communication channel can destroy the UAV or distort data received from it. To solve this problem, an exchange protocol with the ability to protect transmitted information is required the core of this protocol is an encryption algorithm, based on which the algorithms for protecting the integrity, confidentiality and availability of the transmitted data for the UAV are implemented. The structure of the protocol for the secure exchange of information was developed. The selection of the hardware platform for the implementation of the software-hardware module of the protocol has been made. The results of cryptanalysis showed the feasibility of using an encryption algorithm in the protocol. The parameters of the protocol are determined, the protocol’s configuration methodology is formulated depending on the possible data exchange channels in order to ensure the maximum permissible level of protection of the transmitted information, taking into account the characteristics of each channel. According to the results of this work, we can conclude that the proposed encryption algorithm is better resistant to cryptanalysis than other widely used algorithms.
