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.

Strategies designed to deal with these challenges differ in the way in which added duties are assigned and cybersecurity topics are integrated into the already existing process steps. Cybersecurity requirements often clash with existing system requirements or established development methods, leading to low acceptance among developers, and introducing the need to have clear policies on how friction between cybersecurity and other fields is handled. ...Cybersecurity requirements often clash with existing system requirements or established development methods, leading to low acceptance among developers, and introducing the need to have clear policies on how friction between cybersecurity and other fields is handled. A cybersecurity development approach is frequently perceived as introducing impediments, that bear the risk of cybersecurity measures receiving a lower priority to reduce inconvenience. ...For an established development process and a team accustomed to this process, adding cybersecurity features to the product initially means inconvenience and reduced productivity without perceivable benefits.

This paper is the second in the series of documents designed to record the progress of a series of SAE documents - SAE J2836™, J2847, J2931, & J2953 - within the Plug-In Electric Vehicle (PEV) Communication Task Force. This follows the initial paper number 2010-01-0837, and continues with the test and modeling of the various PLC types for utility programs described in J2836/1™ & J2847/1. This also extends the communication to an off-board charger, described in J2836/2™ & J2847/2 and includes reverse energy flow described in J2836/3™ and J2847/3. The initial versions of J2836/1™ and J2847/1 were published early 2010. J2847/1 has now been re-opened to include updates from comments from the National Institute of Standards Technology (NIST) Smart Grid Interoperability Panel (SGIP), Smart Grid Architectural Committee (SGAC) and Cyber Security Working Group committee (SCWG).

Communication between Plug-in Vehicles and the Utility Grid

This paper is the first in a series of documents designed to record the progress of the SAE J2293 Task Force as it continues to develop and refine the communication requirements between Plug-In Electric Vehicles (PEV) and the Electric Utility Grid. In February, 2008 the SAE Task Force was formed and it started by reviewing the existing SAE J2293 standard, which was originally developed by the Electric Vehicle (EV) Charging Controls Task Force in the 1990s. This legacy standard identified the communication requirements between the Electric Vehicle (EV) and the EV Supply Equipment (EVSE), including off-board charging systems necessary to transfer DC energy to the vehicle. It was apparent at the first Task Force meeting that the communications requirements between the PEV and utility grid being proposed by industry stakeholders were vastly different in the type of communications and messaging documented in the original standard.

2021-01-0183
Software vulnerability management is one of the most critical and crucial security techniques, which analyzes the automotive software/firmware across the digital cockpit, ADAS, V2X, etc. domains for vulnerabilities, and provides security patches for the concerned Common Vulnerabilities and Exposures (CVE). The process of automotive SW/FW vulnerability management system between the OEMs and vendors happen through a channel of fixing a certain number of vulnerabilities by 1st tier supplier which needs to be verified in front of OEMs for the fixed number and type of patches in there deliverable SW/FW. The gap of verification between for the fixed patches between the OEMs and 1st tier supplier requires a reliable human independent intelligent technique to have a trustworthiness of verification.

Hardware Protected Security for Ground Vehicles

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.

Improvement of the Resilience of a Cyber-Physical Remote Diagnostic Communication System against Cyber Attacks

2019-04-02
2019-01-0112
In the near future, vehicles will operate autonomously and communicate with their environment. This communication includes Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I) communication, and comunication with cloud-based servers (V2C). To improve the resilience of remote diagnostic communication between a vehicle and external test equipment against cyberattacks, it is imperative to understand and analyze the functionality and vulnerability of each communication system component, including the wired and wireless communication channels. This paper serves as a continuation of the SAE Journal publication on measures to prevent unauthorized access to the in-vehicle E/E system [9], explains the components of a cyber-physical system (CPS) for remote diagnostic communication, analyzes their vulnerability against cyberattacks and explains measures to improve the resiliance.

Megatrends - Connectivity and Automation Expanding the Boundaries of Personal Mobility: Technology Leadership Brief

2012-10-08
2012-01-9026
Personal mobility is being transformed by the advent of vehicle connectivity and automation. While significant individually, their interrelationships promise to bring unprecedented levels of traffic efficiency. Car-makers are talking about a crash-less society and transportation engineers are talking about the end of congestion - a tall order indeed: can this really be? In this decade we can expect to see the effects of sensor-based active safety systems bringing the crash rate down, as these technologies continue to expand across a wider range of vehicle models. Connectivity for infotainment purposes is already a major market driver, and control assist for convenience purposes is laying the groundwork for semi-automated and automated driving. Direct vehicle-vehicle connectivity opens up new capabilities. What is the government role in these developments - an essential player or a bystander? How can they enable or inhibit market activity in these domains?

Pseudonym Issuing Strategies for Privacy-Preserving V2X Communication

2020-08-18
Abstract Connected vehicle technology consisting of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication falls under the umbrella of V2X, or Vehicle-to-Everything, communication. This enables vehicles and infrastructure to exchange safety-related information to enable smarter, safer roads. If driver alerts are raised or automated action is taken as a result of these messages, it is critical that messages are trustworthy and reliable. To this end, the Security Credential Management System (SCMS) and Cooperative Intelligent Transportation Systems (C-ITS) Credential Management System (CCMS) have been proposed to enable authentication and authorization of V2X messages without compromising individual user privacy. This is accomplished by issuing each vehicle a large set of “pseudonyms,” unrelated to any real-world identity. During operation, the vehicle periodically switches pseudonyms, thereby changing its identity to others in the network.
