Abstract
The present invention relates to a system and method for protecting transmitted data in a vehicle control system, comprising of a vehicle or navigation device and a control module communicatively connected to the navigation device according to NMEA standard; and an encryption/decryption unit integrated in the navigation device and in the control module including an AES128 block encryption algorithm in a Cipher Feedback mode (CFB mode), wherein the unit including instructions to encrypt/decrypt data transmitted between the navigation device and the control module.
Claims20
A system for protecting transmitted data in a vehicle control system, comprising:
- a vehicle or navigation device and a control module communicatively connected to the navigation device according to NMEA standard;
- and
- an encryption/decryption unit integrated in the navigation device and in the control module including an AES128 block encryption algorithm in a Cipher Feedback mode (CFB mode), the unit including instructions to encrypt/decrypt data transmitted between the navigation device and the control module.
A method for protecting data in a vehicle control system, comprising:
- determining, in a vehicle or navigation device, data for sending to one or more control modules, wherein the data includes a set of geographical coordinates of the navigation device;
- encrypting the data using an AES128 block encryption algorithm in a Cipher Feedback mode (CFB mode);
- sending the encrypted data according to NMEA standard to the one or more control modules for decryption by the one or more control modules using the AES128 block encryption algorithm in the CFB mode;
- and
- wherein the method applies to the geographical coordinates and to all NMEA protocol data traffic.
