In the Internet of Things, cars must be able to defend themselves

Arxan takes its name from an aviation incident, in which a US plane went down in the Arxan Region of Inner Mongolia, China. As Chief Technical Officer Sam Rehman explains, the Chinese government did what any government would do and took apart the software to see what it could learn. This raised concerns over data security at the US Department of Defence, which in the wake of the incident recognised an urgent need to make software self-protecting. Such action prevents third parties from learning how software works and reusing it, or worse, transforming it into a weapon capable of physical damage.
