Multi-Zone Authentication and Privacy-Preserving Protocol (MAPP) Based On the Bilinear Pairing Cryptography for...

Area of Science:

• Cybersecurity
• Telecommunications Engineering
• Automotive Technology

Background:

• 5G-Vehicle-to-Everything (5G-V2X) requires robust security for autonomous services.
• Existing Public Key Infrastructure (PKI) solutions for C-V2X face communication and computation overhead challenges.
• The 3GPP Release 16 standard suggests reusing IEEE1609.2 for C-V2X security.

Purpose of the Study:

• To propose an efficient and lightweight security solution for 5G-V2X multi-zone broadcast authentication.
• To address the high overhead associated with PKI-based security in C-V2X.
• To develop a protocol that meets 5G requirements for low latency and high reliability.

Main Methods:

• Proposed a lightweight Multi-Zone Authentication and Privacy-Preserving Protocol (MAPP) utilizing bilinear pairing cryptography.
• Developed three distinct authentication methods for secure broadcast authentication across multiple zones with a single message and short signature.
• Introduced a centralized dynamic key generation method for multi-zone environments.

Main Results:

• The MAPP protocol significantly reduces signature generation time (16x-80x) and verification time (10x-16x) compared to previous methods.
• Achieved substantial speed-up in both signature generation and verification using short bilinear pairing signatures.
• Demonstrated efficiency through implementation and analysis using an authentication simulator and a bilinear pairing library.

Conclusions:

• The proposed MAPP protocol offers an efficient and secure solution for 5G-V2X multi-zone broadcast authentication.
• Bilinear pairing cryptography enables a lightweight approach, overcoming the overhead limitations of traditional PKI.
• The protocol enhances the feasibility of secure and reliable autonomous driving services over 5G networks.
