As vehicles become increasingly connected with the external world, they face a growing range of security vulnerabilities. Researchers, hobbyists, and hackers have compromised security keys used by vehicles' electronic control units (ECUs), modified ECU software, and hacked wireless transmissions from vehicle key fobs and tire monitoring sensors. Malware can infect vehicles through Internet connectivity, onboard diagnostic interfaces, devices tethered wirelessly or physically to the vehicle, malware-infected aftermarket devices or spare parts, and onboard Wi-Fi hotspot. Once vehicles are interconnected, compromised vehicles can also be used to attack the connected transportation system and other vehicles. Securing connected vehicles impose a range of unique new challenges. This paper describes some of these unique challenges and presents an end-to-end cloud-assisted connected vehicle security framework that can address these challenges.

This paper presents modeling, analysis, and results of the business viability of a set of IntelliDrive 1 safety applications in a free market setting. The primary value drivers for motorists to adopt the IntelliDrive system are based on a set of safety applications developed and analyzed by the US DOT. The modeling approach simulates IntelliDrive on-board equipment adoption by motorists based on the value of the safety applications. The simulation model uses parameters that are based on adoption rates in a similar dynamical system from recent history and incorporates feedback loops such as the positive reinforcement of vehicle-to-vehicle applications value due to increased adoption. This approach allows the analysis of alternative IntelliDrive business approaches, deployment scenarios, and policies. The net present value of the IntelliDrive system to the nation is computed under alternative scenarios.

Telematics is the gradual fusion of mobile wireless, vehicular communications, and computing technologies to improve transportation safety, mobility, efficiency, and to make driving more comfortable and enjoyable. The driving forces for telematics are the increasing congestion and dangers of the roads and highways, the ubiquity of mobile wireless communication, and the intense competition in the automotive industry. This paper envisions an open, flexible, and wireless access technology-agnostic Telematics Services Architecture that supports telematics applications in diverse and dynamic business environments in a cost effective manner. It first presents a framework of such an architecture and identifies its fundamental functional elements.
