Area of Science:

• Computer Science
• Cryptography
• Network Security

Background:

• Vehicular Ad-Hoc Networks (VANETs) face growing communication demands due to smart city and intelligent vehicle development.
• Internet of Vehicles (IoV) requires low-latency, secure authentication and key agreement protocols.
• Traditional protocols are inefficient and unsuitable for resource-constrained VANETs.

Purpose of the Study:

• To propose a lightweight identity authentication and group key agreement scheme for vehicle-road coordination.
• To leverage Semiconductor Superlattice Physically Unclonable Function (SSL-PUF) for enhanced cryptographic applications.
• To provide information-theoretical security proofs for the proposed scheme.

Main Methods:

• Development of a novel identity authentication protocol based on SSL-PUF.
