LBVP: A Lightweight Batch Verification Protocol for Fog-Based Vehicular Networks Using Self-Certified Public Key Cryptography

To achieve efficient vehicular network communication and service, researchers proposed fog-based networks (FVNs). One of the prerequisites for developing large-scale FVNs is ensuring security privacy entire environment. However, existing schemes exist considerable calculation costs and/or vulnerabilities. Therefore, to promote FVN authentication, we propose a lightweight protocol using self-certified public key cryptography. In protocol, trusted authority does not need participate in authentication process between vehicle fog node online. And can dynamically update its login password pseudonym, without performing complicated interactive steps with authority. addition, our supports batch verification, which significantly improves system efficiency. A detailed analysis reveals that meet requirements while resisting common types attack. Calculation overhead comparisons further prove exhibits better performance than related schemes.
