Well, I do think this is a solution. The author's point, as I interpreted it, is that automakers will not be exempted from following the well-proven, well-understood authentication process. Cumbersome it may be, there will be no shortcuts.
The title of this post is "solving... " but there weren't a lot of solutions -- or any -- given. The answer it seems is that we secure inter-car communications the same inefficient and relatively easily hacked way that we secure the internet. Doesn't really give me a lot of hope.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
