Connected vehicles have been the focus of much research from an engineering and from a security point of view. They are the mechanism behind Safety Applications, aiming to reduce accidents. Now these technologies are close to arriving in vehicles. News like "General Motors Promotes DSRC for Connected Vehicle (V2X) Technology Development in China", signaling the arrival of a DSRC equipped Cadillac CTS in 2017, or "2017 Audis Will Talk To Some Traffic Signals, Kicking Off Vehicle-To-Infrastructure Communications" indicate that the games have started. Whether one talks about DSRC or cellular technologies implementing the Vehicle-to-Vehicle, Vehicle-to-Infrastructure or Vehicle-to-Pedestrian communication, one question is clear: How will these wireless technologies, which inherit the full attack vector of wireless communication, survive in hostile environments? Alternatively: What does it take to develop safety applications that can survive in such environments? After all, when we are talking about V2X technologies we need to remember that they operate in a safety critical infrastructure where failure of safety applications could spell out injury, death, and loss of public confidence.
