Guaranteed security and trustworthiness in transportation cyber-physical systems

摘要: Transportation cyber-physical systems (CPSs) have the potential to improve traffic safety, mobility, and environmental protection. However, they are subject to threats stemming from increasing reliance on information and communication technologies (ICT). Cybersecurity threats exploit the increased complexity and connectivity of the transportation-critical infrastructure system, placing the transportation at risk. This chapter reviews the state of the art and the state of the practice of CPS in various transportation sectors, including highway, railway, and air. This chapter also examines various cybersecurity threats to the transportation CPS and the current countermeasures to enhance cybersecurity of these CPS. It then discusses several challenges and opportunities in achieving secure and trustworthy transportation CPS.
