A Comprehensive Attack and Defense Model for the Automotive Domain

Technical University of Munich, Germany-Thomas Hutzelmann, Sebastian Banescu, Alexander Pretschner
  • Journal Article
  • 11-02-01-0001
Published 2019-01-17 by SAE International in United States
In the automotive domain, the overall complexity of technical components has increased enormously. Formerly isolated, purely mechanical cars are now a multitude of cyber-physical systems that are continuously interacting with other IT systems, for example, with the smartphone of their driver or the backend servers of the car manufacturer. This has huge security implications as demonstrated by several recent research papers that document attacks endangering the safety of the car. However, there is, to the best of our knowledge, no holistic overview or structured description of the complex automotive domain. Without such a big picture, distinct security research remains isolated and is lacking interconnections between the different subsystems. Hence, it is difficult to draw conclusions about the overall security of a car or to identify aspects that have not been sufficiently covered by security analyses. In this work, we propose a comprehensive model covering all relevant aspects of the automotive environment and link it with selected attack scenarios and defense strategies already discussed in academic literature. This showcases the capabilities of our model to build…

Securing the Secret Key

KPIT Technologoes-Narendra Kumar SS
  • Technical Paper
  • 2019-01-0097
Published 2019-01-16 by SAE International in United States
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 driver-less cars; connected cars are no more a work of mere research. 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.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.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. This depends on the strength of the secret key used to encrypt the messages. In an automobile, these secret keys will be inside the automobile itself. If the…

Instantaneous Driver Safety Assistance and Rear Wheel Maneuvering system based on Computer Vision

Delhi Technological University-Joy Sengupta
  • Technical Paper
  • 2019-01-0095
Published 2019-01-16 by SAE International in United States
The paper presents the ideology, concept, design of a prototype based on the adaptive rear-steering of a vehicle to counter under steer especially at corners at very high speeds, to further decrease to a shorter turning radius, improvement in agility at tighter spaces and for example parallel strafe parking and also immediate response to driver steering feedback via the rear axle. The technology domains utilized in the technology are classified based on the two modules of the system: Sensor Unit - Marker Identification, in this case chessboard or ArUco marker, Computer Vision and mathematical processing in OpenCV and in Python. Various mathematical concepts are used in the sensing system for accurate detection of axes and calculation of steering angles, and if possible, wheel damping and rebound for suspension stiffening. Rear Axle Control Unit - Data processed from Sensor Unit is fed to a control system including a microcontroller, rear steering mechanism and also on further development, a rear or four wheel adaptive suspension system based on magnetorheological or fluid based damping. This approach of a…

Optimization of vehicle operating conditions using AnyLogic

Kherson State Maritime Academy-Igor Gritsuk
Ukrainian State Univ. of Railway Transp-Mykyta Volodarets, Nataliia Chygyryk
  • Technical Paper
  • 2019-01-0099
Published 2019-01-16 by SAE International in United States
The paper describes the process of modeling and optimizing the operating conditions of vehicles for a section of the transport network using simulation tools. The cyphergrams of the transport flow intensities in the transportation hub were built, a graphic model of vehicle traffic in the transportation hub was built, and a transition probability matrix was compiled, which was used to simulate modeling and optimize vehicle operating conditions for the considered transport hub. AnyLogic software was chosen for simulation. It supports all simulation methods and a powerful built-in library for traffic modeling. The corresponding simulation model was created. With the help of it, modeling in the transport node selected for research has been carried out and the optimum values of the duration of the phases of traffic light objects have been obtained. This has reduced the average travel time through the site, which is considered in the work, and the number of cars in traffic jams. In the process of modeling, the objective function is formed with the corresponding restrictions. Also, the task of optimizing operating…
