Anonymity Assurance Using Efficient Pseudonym Consumption in Internet of Vehicles.

Area of Science:

• Computer Science
• Network Security
• Transportation Systems

Background:

• Internet of Vehicles (IoVs) enable vehicle communication for safety.
• Basic Safety Messages (BSM) contain sensitive data, vulnerable to adversaries.
• Current pseudonym management in IoVs is inefficient, leading to high consumption and message loss.

Purpose of the Study:

• To propose an Efficient Pseudonym Consumption Protocol (EPCP) for IoVs.
• To reduce pseudonym consumption and Basic Safety Message (BSM) loss.
• To enhance security and efficiency in vehicular communication networks.

Main Methods:

• Developed EPCP considering vehicles in the same direction and similar estimated locations.
• Implemented and simulated the EPCP against base schemes.
• Validated performance through extensive simulations.

Main Results:

• EPCP significantly reduced pseudonym consumption compared to base schemes.
• The proposed protocol demonstrated a lower Basic Safety Message (BSM) loss rate.
• EPCP achieved better traceability performance.

Conclusions:

• EPCP offers an efficient solution for pseudonym management in IoVs.
• The protocol enhances network security and reduces communication overhead.
• EPCP is a promising approach for improving the reliability of vehicular communication.
