The Onboard Diagnostics Port (OBD) has been required for all cars sold in the US since 1996 and in Europe since 2001. Prompted by the need to simplify the diagnosis of increasingly complex emission control systems, the OBD-II improved on previous implementations by providing standardized condition codes for the auto repair and tuning markets. Standardized access to this data has helped spawn a robust aftermarket of plug-in devices to allow consumers to monitor their teen drivers, earn discounts from insurers, or gain insights into the performance and health of their vehicles. Similar devices allow fleet managers to monitor the condition, performance and behavior of their vehicles. Nearly all of these dongles offer a wireless connection for the convenience of their customers. Unfortunately, a wireless connection also provides a potential path for hackers to gain entry to the car’s internal networks.
There are four primary use cases for implementing trusted computing with a Trusted Platform Module (TPM), the cryptographic module standardized by the Trusted Computing Group. This blog will give a brief overview of those use cases, which can be combined to create more complex and powerful solutions.
There are two worlds of computer security - high-end systems and then everything else. Both high- and low-end systems typically employ “top-down” defenses to harden their attack surfaces. These are “software-only” security techniques.
At the Automated Vehicles Symposium (AVS) 2017, I addressed a plenary talk to the ~1,500 attendees, stating that even though it is unanimously considered as paramount, cybersecurity is still an after-thought. Or at least it still feels like it. Indeed, for the last two AVS editions, the cybersecurity breakout session reported similar open challenges, but no real changes have been seen since. In order to move the security needle, we took a different approach and didn't organize a cybersecurity breakout session. Instead, we identified that the missing components were the lack of inputs coming from the community of experts. To be able to build a more resilient system, cybersecurity experts should know about the limitations of each subsystem, and possible "nightmare scenarios".

Car makers use cryptographic keys for a variety of purposes, including Over-The-Air (OTA) software updates, security immobilizers, inter-module communications, and Vehicle-to-Everything (V2X) communication security. Key Management Systems (KMS) are very complex, as the manufacturer has to manage dozens of keys for each car model, both at production and when new components are introduced during repairs, and they must maintain these keys over the long lifetime of a car. Key Management is a daunting task.
The IoT, or the "Internet of Things," represents an exciting period of innovation in our lives. It describes a world of devices all connected to the internet, a world in which inanimate technology that we use and see every day is becoming smarter. It also predicts a continuous journey towards greater ease and convenience, a future in which technology interacts with us as much as we do with it. As you can imagine, this comes with both perks and drawbacks.
