Positioning Information Privacy in Intelligent Transportation Systems: An Overview and Future Perspective

Area of Science:

• Intelligent Transportation Systems (ITS)
• Vehicular Communication
• Cybersecurity

Background:

• ITS are integrating globally, with vehicle positioning crucial for operation.
• GPS limitations in certain areas necessitate advanced positioning solutions.
• Vehicular communication standards like DSRC and ETSI ITS-G5 offer positioning enhancement opportunities.

Purpose of the Study:

• To survey existing vehicle positioning methods in ITS.
• To identify potential security vulnerabilities and attacks on ITS positioning data.
• To propose improvements for secure and private positioning in V2X scenarios.

Main Methods:

• Literature review of vehicle positioning techniques.
• Analysis of security threats and attack vectors in ITS.
• Proposal of mutual authentication mechanisms for V2X communication.

Main Results:

• ITS integration relies heavily on accurate vehicle positioning.
• Existing ITS infrastructure and emerging technologies like 5G can augment positioning.
• Security vulnerabilities exist in current ITS communication protocols, risking positioning data integrity.

Conclusions:

• Mutual authentication between vehicles and infrastructure is vital for securing positioning data.
• Enhancing ITS security through improved protocols is necessary for reliable V2X operations.
• Further development and standardization are needed for secure ITS positioning systems.
