Vehicular ad-hoc security improvements using decentralised consensus blockchain

Abstract

For safer roads, a more efficient driving experience, and protection against attackers, the intelligent cars communicate with one another or with the roadside unit (RSU). The fundamental security requirements of Vehicular Ad-hoc Networks (VANETs) must be nonrepudiable, genuine, and incorporate these three. Additionally, protecting against attackers should be done in particular specific situations. However, the VANET's main disadvantages are its centralized design and the absence of procedures for ensuring confidentiality and privacy. In this paper, proposed decentralised consensus blockchain architecture for VANET that uses blockchain technology to address these problems. The VANET no longer needs a central authority or third-party administration thanks to the introduction of the blockchain. In order to ensure data integrity and accelerate up system processing, the hash value of the pseudonyms will be recorded on the blockchain. By eliminating trust difficulties between the entities, this effectively addresses challenges that arise in centralised designs. The suggested method for VANETs security. Experimental investigation demonstrates that the provided architecture outperforms the available options in terms of security enhancement.
