Abstract
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.
