Enhanced Trust & Risk Based Access Control, in Autonomous Vehicles, by Using Ethereum vs Hyperledger Platforms Consensus Algorithms

Abstract

Blockchain is an emerging technology for data security, integrity and secure communication in the networks of autonomous vehicles (AVs), this technology is extremely utilized for the AV s applications to record the access control data. The aim of this work is to share the knowledge on the growing demand of blockchain technology for the autonomous vehicles, discuss the consequences of integration of blockchain technology in AVs networks and access control systems for autonomous vehicles. This work offers a comprehensive investigation of existing applications for AVs based on blockchain technology with respect to various aspects including secure communication channels, forensics applications, secure data storage, reputation and trust management, data integrity and privacy. This work also offers an extensive study on various types of consensus algorithms used in Ethereum/Hyperledger, and provides a comprehensive comparison of trust and risk based on blockchain consensus algorithms on Ethereum over Hyperledger for autonomous vehicle applications.
