BPPCP: Block chain-based privacy-preserving communication protocol for VANETs

Vehicular Ad-hoc network (VANET) enhances traffic safety and efficiency by broadcasting traffic related messages wirelessly. Secure and safe communication among moving nodes of VANET, privacy, mutual authentication and non- repudiation are the most important security requirements. Therefore pre-serving these security goals, we develop an efficient andsecure communication system model for as a BPPCP Protocol for VANET. This system model work through cryptographic primitive scheme. In this system we provide security among moving nodes of VANET. This system uses an additional feature of Smart Content, which makes it unique from existing systems by providing some extra security features.
