The described techniques facilitate the secure transmission of sensor measurement data to an ECU by implementing an authentication procedure. The authentication procedure includes an integrated circuit (IC) generating authentication tags by encrypting portions of sensor measurement data. These authentication tags are then transmitted together with the sensor measurement data as authenticated sensor measurement data. The ECU may then use the authentication tags to authenticate the sensor measurement data based upon a comparison of the portions of the sensor measurement data sensor measurement data to the authentication tag that is expected to be generated for those portions of sensor measurement data.
