An electronic control unit comprises circuitry to receive a combined signal via a vehicle bus of a vehicle, wherein the combined signal contains a combination of a data signal and a watermark signal, which can be a radio frequency (RF) signal or an analog baseband signal, wherein the data signal includes a message, circuitry to extract a watermark from the watermark signal, circuitry to verify the watermark based on a comparison of the watermark with a pre-defined watermark, circuitry to extract the data signal from the combined signal and obtain the message from the data signal, and circuitry to authenticate the message based on the verification of the watermark.

Vehicle bus message authentication using watermarking

A first connected message broadcast from a first vehicle and a second connected message broadcast from a second vehicle is received, each of the first and second connected messages including proof-of-work computed from connected vehicle data regarding a third vehicle. The first and second connected messages are authenticated, responsive to a comparison of the proof-of-work for the third vehicle included in the first connected message and the proof-of-work for the third vehicle included in the second connected message. The connected vehicle data in the first connected message broadcast or second connected message broadcast is utilized for autonomous vehicle operations or driver-assistance vehicle operations, responsive to the proof-of-work being a match.

Proof-of-work vehicle message authentication

A computer includes a processor and a memory, the memory storing instructions executable by the processor to arrange data collected by a plurality of sequentially arranged emitters in a sensor according to a nonsequential numerical order of the emitters, transmit the nonsequential numerical order to a vehicle computer according to a secure protocol, and transmit the data to the vehicle computer.

Vehicle sensor operation

A vehicle-to-vehicle communication system includes a controller programmed to digitally sign each of a plurality of basic safety messages (BSMs) using a private key and broadcast each of the BSMs via the transceiver at respective transmit power levels according to a predetermined power level sequence that is defined by one or more values generated from the private key.
