The recently released SAE J3061 guidebook for cyber-physical vehicle systems provides high-level principles for automotive organizations for identifying and assessing cybersecurity threats and for designing cybersecurity aware systems in close relation to the ISO 26262 standard for the functional safety of road vehicles. ...., infotainment, car-2-car or car-2-infrastructure communication) as well as new advances toward advanced driver assistance systems (ADAS) or even autonomous driving functions make cybersecurity another key factor to be taken into account by vehicle suppliers and manufacturers. ...Although these can capitalize on experiences from many other domains, they still have to face several unique challenges when gearing up for specific cybersecurity challenges. A key challenge is related to the increasing interconnection of automotive systems with networks (such as Car2X).

Introduction to Highly Automated Vehicles

2020-12-07
Every year, the U.S. on average, experiences more than 34,000 traffic deaths and over 5 million vehicle crashes. While the trend in traffic deaths has been generally downward for the past decade, most of this reduction has been the result of optimizing passive occupant crash protection systems such as seatbelts and airbags. Highly automated vehicle's (HAV's) offer the potential to significantly reduce vehicle crashes by perceiving a dangerous situation before the crash has occurred and supporting the human driver with proactive warnings and in some cases active interventions to avoid or mitigate the crash.

Safe and Secure Development: Challenges and Opportunities

2018-04-03
2018-01-0020
The ever-increasing complexity and connectivity of driver assist functions pose challenges for both Functional Safety and Cyber Security. Several of these challenges arise not only due to the new functionalities themselves but due to numerous interdependencies between safety and security. Safety and security goals can conflict, safety mechanisms might be intentionally triggered by attackers to impact functionality negatively, or mechanisms can compete for limited resources like processing power or memory to name just some conflict potentials. But there is also the potential for synergies, both in the implementation as well as during the development. For example, both disciplines require mechanisms to check data integrity, are concerned with freedom from interference and require architecture based analyses. So far there is no consensus in the industry on how to best deal with these interdependencies in automotive development projects.

Hardware Protected Security for Ground Vehicles

2020-02-10
CURRENT
J3101_202002
Access mechanisms to system data and/or control is a primary use case of the hardware protected security environment (hardware protected security environment) during different uses and stages of the system. The hardware protected security environment acts as a gatekeeper for these use cases and not necessarily as the executor of the function. This section is a generalization of such use cases in an attempt to extract common requirements for the hardware protected security environment that enable it to be a gatekeeper. Examples are: Creating a new key fob Re-flashing ECU firmware Reading/exporting PII out of the ECU Using a subscription-based feature Performing some service on an ECU Transferring ownership of the vehicle Some of these examples are discussed later in this section and some have detailed sections of their own. This list is by no means comprehensive.

Research on CAN Network Security Aspects and Intrusion Detection Design

2017-09-23
2017-01-2007
With the rapid development of vehicle intelligent and networking technology, the IT security of automotive systems becomes an important area of research. In addition to the basic vehicle control, intelligent advanced driver assistance systems, infotainment systems will all exchange data with in-vehicle network. Unfortunately, current communication network protocols, including Controller Area Network (CAN), FlexRay, MOST, and LIN have no security services, such as authentication or encryption, etc. Therefore, the vehicle are unprotected against malicious attacks. Since CAN bus is actually the most widely used field bus for in-vehicle communications in current automobiles, the security aspects of CAN bus is focused on. Based on the analysis of the current research status of CAN bus network security, this paper summarizes the CAN bus potential security vulnerabilities and the attack means.

Assuring Vehicle Update Integrity Using Asymmetric Public Key Infrastructure (PKI) and Public Key Cryptography (PKC)

2020-08-24
Abstract Over the past forty years, the Electronic Control Unit (ECU) technology has grown in both sophistication and volume in the automotive sector, and modern vehicles may comprise hundreds of ECUs. ECUs typically communicate via a bus-based network architecture to collectively support a broad range of safety-critical capabilities, such as obstacle avoidance, lane management, and adaptive cruise control. However, this technology evolution has also brought about risks: if ECU firmware is compromised, then vehicle safety may be compromised. Recent experiments and demonstrations have shown that ECU firmware is not only poorly protected but also that compromised firmware may pose safety risks to occupants and bystanders.

Securing the Secret Key

2019-01-16
2019-01-0097
Recent advances in automotive technologies have paved way to a new era of connectivity. Advanced Driver Assistance Systems are getting deployed in automobiles; many companies are developing driverless cars; connected cars are no more a work of mere research. [1] Vehicle manufacturers are developing ways to interface mobile devices with vehicles. However, all these advances in technology has introduced security risks. Unlike traditional computing systems, the security risk of an automobile can be fatal and can result in loss of lives [2]. The in-vehicle network of an automobile was originally designed to operate in a closed environment and hence network security was not considered during its design [3]. Several studies have already shown that an in-vehicle network can be easily compromised and an intruder can take full control of the vehicle. Researchers are working on various ways to solve this problem. Securing the in-vehicle communication by encrypting the messages is one such way.

Making sense of autonomy Industry offers a range of sensors that will free humans from many tasks while also improving reliability, though devising strategies that meet demanding requirements without breaking the bank is no easy challenge. Life-cycle planning-Design and calibration for ultimate efficiency The ultimate power of Big Data technologies relies on the implementation of new strategies. Unlike a traditional engine calibration process, in which only calibration test data and model simulation data are used, multiple source data introduced into the adaptive engine calibration process contributes to efficiency and cost reduction. The complicated future of off-highway engines Developing an optimum engine is getting tricky now that the European Union has established a Stage V for off-highway engines, and the U.S. has not. What effect will this have on future engine designs?
