@dvk0, well, certinaly this is a cool video. What it shows, though, is not necessarily an answer to the question whether a car or a ship can be hacked; it is about where the weak link resides within any system that an attacker can go after. In this particular case, it is clearly the GPS. In the case of cars, it wasn't GPS, but there are a number of other attack surfaces that researchers exposed.
May be you are right, but Cars are not being controlled by GPS. And Securing the car from all known threats it responsibility of the manufacturer, so this thread of security enhancement will any way continue.
Yes, It was a very good source of information, SHE (Secure Hardware Extension) and EVITA, are the emerging standards for Automotive Electronic Security, and it was a very surprising to me that virtually all the electronics giants are working on it name it a few like Mentor Graphics, Toshiba, Freescale, Renesas and the list continues.
You are right SHE enabled automotive electronics will be soon getting seen in the general automobiles.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
