EAIA: An Efficient and Anonymous Identity-Authentication Scheme in 5G-V2V.

Area of Science:

• Computer Science
• Network Security
• Cybersecurity

Background:

• Vehicle Ad-hoc Networks (VANETs) are vital for safer, efficient driving through inter-vehicle communication.
• Vehicle-to-Vehicle (V2V) communication enhances safety and traffic efficiency but faces challenges beyond roadside unit (RSU) range.
• Limited onboard unit (OBU) computational resources necessitate lightweight security protocols for V2V.

Purpose of the Study:

• To propose an efficient anonymous V2V identity-authentication protocol for RSU-less environments.
• To address security vulnerabilities in V2V communication when vehicles are outside RSU range.
• To develop a lightweight protocol suitable for the constrained computational resources of vehicle OBUs.

Main Methods:

• Formal security assessment using the Scyther tool.
• Development of an anonymous V2V identity-authentication protocol.
• Performance evaluation of communication and computational overhead.

Main Results:

• The proposed protocol effectively withstands common malicious attacks.
• Formal verification confirms the protocol's security guarantees.
• Performance evaluations demonstrate low communication and computational overhead.

Conclusions:

• The developed protocol offers a viable and efficient security solution for RSU-less V2V communication.
• It enhances the security and reliability of VANETs, supporting autonomous driving systems.
• The protocol's lightweight nature makes it suitable for practical implementation in vehicles.
