The first design is to use the loud siren. When any illegal intrusion happens, the siren will sound loudly to warn the intruder. The second design is to use an immobilisation system to disable the engine start. With the peripheral devices, the system can provide the following main protection: • Ignition trigger: illegally turn IGNITION ON, the alarm will be triggered. • Boot trigger: illegally open the boot, the alarm will be triggered. • Door trigger: illegally open the door, the alarm will be triggered. • AUX trigger: it can be used on any other additional sensor, e.g. bonnet trigger.

  • Security in Smart Cyber-Physical Systems
    CHAPTER 11 Security in Smart Cyber-Physical Systems: A Case Study on Smart Grids and Smart Cars Sandeep Nair Narayanan*, Kush Khanna†, Bijaya Ketan Panigrahi†, and Anupam Joshi* *University of Maryland Baltimore County, Baltimore, MD, United States †Indian Institute of Technology Delhi, New Delhi, India 1 INTRODUCTION Across the globe, cities are expanding in size and infrastructure. The idea of Smart Cities plays a vital role in offering higher efficiency, comfort, awareness, and convenience to end users. Harrison et al. [1] describe the Smart City as an instrumented, interconnected, and intelligent city. They instrument different sectors of smart infrastructure, such as smart energy, smart transportation, smart governance, smart healthcare, smart buildings, and so forth to capture real- world data and interconnect them to share this data among different services. The shared data is then used to make intelligent operational decisions using complex analytics and provide better facilities to end users. Smart Cyber- Physical Systems (CPSs) are essential components of all smart infrastructure. According to the National Science Foundation (NSF),1 “Cyber-physical systems integrate sensing, computation, control and networking into physical objects and infrastructure, connecting them to the Internet and each other.” Smart cars and smart grids are two CPS domains that have demonstrated tremendous growth over the past few decades. However, the capabilities of these CPSs to influence critical infrastructure make them a lucrative target for hackers. Some of the attacks even have a direct impact on the economy of a nation. For example, consider the attack on the Ukrainian smart grids [2]. It left a whole city without heat and electricity in the cold of December for many hours.

  • A Practical Design of Anti-Theft Car Protection System Based on Microcontroller
    American Journal of Applied Sciences 9 (5): 709-716, 2012 ISSN 1546-9239 © 2012 Science Publications A Practical Design of Anti-Theft Car Protection System Based on Microcontroller Mohammed Abuzalata, Muntaser Momani, Sayel Fayyad and Suleiman Abu-Ein Departments of Mechatronics and Mechanical Engineering, Faculty of Engineering, Al-Balqa’ Applied University, Technology, Amman, Jordan Abstract: Problem statement: This study presents a new design for an anti-theft protection System as an inexpensive solution to protect cars from theft and from non-authorized users by using microcontroller-based system. Approach: Three stages of protection to strengthen the security of the car: Firstly, when the user access the car by the car key and entered the wrong password, the power is remain disable. If the power shifted by others, the second level comes by disabling the starter motor from being turned on, so the stolen keys cannot turn the car on. Results: Assuming that the thief or non-authorized person connected the starter motor directly to the car battery, the car well not turned on because the directional valve is set to the case where the fuel is fed back to the fuel tank and no fuel is pumped into the engine, which is the third security level. Conclusion/Recommendations: A microcontroller is programmed using C language, a directional valve is controlled by microcontroller to take the proper valve position to allow the engine to start or not. This system is worked properly and tested successfully.

  • Security Analysis of Aftermarket Remote Keyless Entry Systems for Consumer Vehicles
    Radboud University Nijmegen Faculty of Science Security Analysis of Aftermarket Remote Keyless Entry Systems for Consumer Vehicles Master Thesis Information Sciences Author: T.W. (Tobias) van Capelleveen S4796497 [email protected] Daily supervisor: C.F.J. (Carlo) Meijer Supervisor: dr. V. (Veelasha) Moonsamy Second Assessor: dr. E. (Erik) Poll March 23rd, 2020 Abstract This research focusses on aftermarket remote keyless entry systems for consumer vehicles and its effects regarding security, once the installation has been performed. To obtain a picture of the level of security of the aftermarket devices, a selection of 5 of them were researched. The devices vary in functionality, protocol and cost. The research uncovered security vulnerabilities in all of them. Known attacks could be applied or fitting exploits were created and tested for most of the devices. The devices were vulnerable for replay attacks and some could be opened/closed by the act of capturing and re-playing a single recording. Other devices required an exhaustive key search for entry, which would last at most 4 hours. The devices with the best security will require substantial effort to crack, but all devices from the same brand are vulnerable to attack with just 2 recordings once the effort has been made (Eisenbarth et al., 2008). Also, the devices with the ‘better’ security can be bypassed by either hot-wiring or a jam-replay attack (Kamkar, 2015). Overall, the security of vehicles will, at best, not become worse by installing an aftermarket remote keyless entry system. The current aftermarket devices use old technologies that are known to be vulnerable.
