FIELD: communication.
SUBSTANCE: invention relates to the tools for protecting data in a vehicle control system according to the NMEA standard. The data in the navigation equipment of the vehicle (V) for sending to one or more control modules is determined, wherein the data includes a set of geographic coordinates of the navigation equipment. The data are encrypted using the AES128 block encryption algorithm in the ciphertext feedback mode (CFB mode). Based on the encrypted data, one or more messages are generated for transmission according to the NMEA standard without changing the structure and order of message fields. The encrypted data are transmitted according to the NMEA standard to one or more control modules to be decrypted by one or more control modules using the AES128 block encryption algorithm in the CFB mode.
EFFECT: higher degree of protection of the vehicle control system against unauthorised attacks.
