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.
In September 2016, the U.S. Department of Transportation (USDOT) awarded three Connected Vehicle (CV) Pilot Deployment Programs: New York City (NYC), Tampa and Wyoming. The CV Pilot Program will test and operationalize cutting-edge vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) technologies, including in-vehicle wireless, mobile devices, and roadside equipment that have the potential to reduce accidents, save lives, improve productivity, enhance mobility, and lessen the environmental impact of city traffic. The NYC CV pilot will feature an estimated 8,000 vehicles outfitted with V2X equipment, including 5,850 taxis, 1,250 MTA vehicles, 400 UPS trucks, and 500 city vehicles. There will be approximately 350 roadside units installed at Manhattan and Brooklyn intersections and on FDR drive. Additionally, 100 vulnerable road user (pedestrians and bicyclists) devices will be deployed to study the effectiveness of V2X technology in reducing NYC's high rate (5 times the national average) of crash fatalities involving pedestrians.
NTRU is a cryptosystem that uses a special type of polynomial ring. The underlying hardness assumption, known as the NTRU assumption, is that an inverse of a short polynomial (polynomial whose coefficients are very short compared to the modulus q) is indistinguishable from a uniformly random polynomial in this ring. This indistinguishability is crucial in designing a cryptosystem.
In July 2016, the Automotive Information Sharing and Analysis Center (Auto-ISAC) released "Automotive Cybersecurity Best Practices" for carmakers and their suppliers. This document expands on their "Framework for Automotive Cybersecurity Best Practices" published in January 2016. This is the first time the automakers have addressed cybersecurity in a formal manner and a strong sign they are treating hacker threats seriously.
