FIELD: radio engineering, communication.

SUBSTANCE: device comprises a setting module configured to define a protocol for transmitting a message stream containing a predetermined set of messages. When specifying the message transfer protocol, the wait state flag is set until a response to the previous request is received and no message is sent before receiving the acknowledgment of the receipt of the previous message, an initializing module configured to initialize the message format for each of the messages. The message format contains a constant-length part and a variable-length part with at least one state table. The state table transfers information from the airborne device to the server, and an installation module configured to establish multi-level protection using at least two security levels attached to the messages and provided to the server and the airborne device. One of the protection levels relates to ensuring the integrity of the message, and the other one of the protection levels refers to the use of encryption to the message.
