Cybersecurity and defense in intelligent transportation systems
Summary Information
Intelligent Transportation Systems (ITS) enhances the efficiency, safety, and security of transportation networks through advanced technologies, though they also pose security and privacy challenges that could leave them vulnerable to cyberattacks and disruptions. This study surveyed the key challenges in securing ITS, outlining engineering requirements, potential attack scenarios, and relevant prior research. It examined core ITS components, including advanced traffic management systems, connected and automated vehicles, intelligent infrastructure, and integrated data analytics. The primary goal was to address the engineering requirements, security threats, and defense mechanisms necessary to ensure the integrity and resilience of ITS in increasingly congested and technologically complex transportation systems.
METHODOLOGY
The study employed a comprehensive literature-based survey and systems analysis to examine cybersecurity and defense mechanisms in ITS. A thematic analysis was conducted to organize findings into key focus areas such as ITS architecture, security vulnerabilities, engineering requirements, and defense strategies. The analysis categorized attack types—such as physical, wireless, and network-based threats—and matched them to corresponding mitigation techniques using both traditional and emerging technologies, including hardware security modules, intrusion detection systems, blockchain, and AI-based adaptive models.
FINDINGS
- Implementing Electronic Control Unit (ECU) architectures for modern vehicles can integrate security and dependability at the design level, which allows resource-limited ITS components to meet real-time automotive control requirements efficiently.
- Privacy-preserving computing ensured the protection of user data while still enabling large-scale traffic analysis.
- Technologies such as blockchain and secure credential systems helped maintain secure, tamper-proof records for transactions, vehicle histories, and communications.
- Integrating security features into hardware architecture allows resource-limited ITS devices to achieve robust protection while sustaining the real-time performance essential for ITS functions.
- Advanced intrusion detection systems (IDS) and machine learning-based anomaly detection enabled ITS to identify cyber threats in real-time and respond rapidly, thereby minimizing the impact of attacks.
- Enhanced cybersecurity for ITS strengthens vehicle connectivity and communication, safeguards user data, improves anomaly detection, and ensures the system continues to reduce crashes and enhance traffic flow through secure, reliable connections.
