A Blockchain-Enabled Incentive Trust Management with Threshold Ring Signature Scheme for Traffic Event Validation in...

Area of Science:

• Intelligent Transportation Systems
• Network Security
• Blockchain Technology

Background:

• Vehicular ad hoc networks (VANETs) are crucial for intelligent transportation systems, offering traffic and road safety information.
• VANETs face significant challenges including malicious attacks, privacy breaches, and lack of trust among nodes.
• Vehicles often lack motivation to validate traffic events, hindering network cooperation.

Purpose of the Study:

• To propose a novel blockchain-enabled incentive trust model for VANETs.
• To address security vulnerabilities, privacy concerns, and lack of cooperation in VANETs.
• To enhance the reliability and trustworthiness of traffic event messages.

Main Methods:

• Implemented a privacy-preserving threshold ring signature scheme for anonymous message authentication.
• Developed a blockchain-enabled incentive trust management model utilizing roadside units (RSUs).
• Employed a practical Byzantine fault-tolerant consensus mechanism for improved efficiency.

Main Results:

• The proposed threshold ring signature scheme ensures anonymous message authenticity and reliability while preserving vehicle privacy.
• The blockchain model effectively thwarts attacks and guarantees the trustworthiness of event messages.
• Incentives motivate participation in traffic information sharing and event validation.

Conclusions:

• The developed system enhances security, trust, and efficiency in VANETs.
• It successfully addresses privacy leakage and malicious attacks in intelligent transportation systems.
• The integration of blockchain and privacy-preserving techniques offers a robust solution for VANET challenges.
