Enhancing Privacy in VANET Cloud: A Blockchain-Powered Identity Authentication Framework

The vehicular ad hoc networks (VANET) based considered a practical resolution for enhancing the current transportation system’s critical situation, due to the advances of intelligent transportation and a wireless local area network. Drivers can adapt the distances between vehicles while planning their route based on current traffic patterns, improving the comprehensive invulnerability and efficacy of the transportation system. Vehicles must broadcast their location information often due to the unique nature of the VANET cloud system service. Adversaries can gather and scrutinize information vehicle communication details to embezzle personal information and even follow the owner’s driving path, posing major security issues. This paper put forth a blockchain established identity validation procedure for VANET cloud. The system combines blockchain technology with the VANET and cloud computing to create a secure and enhance the effectiveness of two-factor identity verification and keys exchange process based on ciphering as well as signature-based algorithms, that can also eliminate the traditional central reliance issue. Performance evaluation confirms that the proposed methodology can be effectively applied for real time applications of VANET cloud.
