Vehicle-to-Vehicle Secure Communication Protocol Based on Digital Vehicle Identification Number

Area of Science:

• Cybersecurity
• Automotive Engineering
• Cryptography

Background:

• Secure vehicular communication is crucial for autonomous driving, smart traffic management, and accident mitigation.
• Public Key Infrastructure (PKI) deployment in vehicular networks presents scalability and efficiency challenges.
• Identity-based cryptography offers a scalable and efficient alternative for secure key management.

Purpose of the Study:

• To propose an identity-based cryptography protocol for vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) communications.
• To replace traditional PKI-based schemes with a VIN-centric identity-based cryptographic approach.
• To demonstrate a prototype implementation and evaluate its performance metrics.

Main Methods:

• Development of a novel communication protocol leveraging identity-based cryptography.
• Utilization of the Vehicle Identification Number (VIN) as a unique vehicle identifier for cryptographic key generation.
• Implementation of a prototype system in a conventional vehicle for real-world testing and performance evaluation.

Main Results:

• Successful proof-of-concept demonstrating the feasibility of the proposed system.
• Quantitative results highlighting the impact of processor performance on encryption/decryption efficiency.
• Validation of secure and flexible vehicle identification capabilities.

Conclusions:

• The proposed identity-based cryptographic system offers a secure and efficient alternative to PKI for V2X communication.
• VIN-based identification streamlines digital authentication, toll payments, and fuel management.
• The system enhances traffic management and safety through improved V2X connectivity.
