An Optimized Decentralized Trust Approach for Securing IoV Stream Data: A Smart Contract-Driven Framework

Abstract

The Internet of Vehicles (IoV) is an emerging technology that enables the real-time sharing of data between vehicles, drivers, and other components of the transportation system. IoV has the potential to improve the overall efficiency and safety of the transportation system. However, it also presents several security and privacy challenges that need to be addressed. Cyberattacks, data breaches, and unauthorized access are some of the significant concerns in the use of IoV. To address these challenges, we propose an optimized decentralized trust approach that uses the Ethereum blockchain to provide a secure and effective method for protecting IoV stream data. The proposed approach involves storing IoV data and necessary files in a SQL server connected to the Ethereum blockchain through a smart contract. The smart contract is used to validate authorized users and store the data in the blockchain network. The blockchain's decentralized nature ensures that the data is available to anyone with the hash address, while the smart contract enhances security by controlling who can access the data. The proposed approach is open-source and utilizes smart contract functionality, making it suitable for various applications. The proposed approach's key advantage is that it addresses security and privacy concerns in IoV data management by leveraging blockchain technology. By using the Ethereum blockchain, we can establish a secure and decentralized framework for data sharing and storage. Furthermore, the use of a smart contract ensures the validity and authenticity of transactions and ensures that only authorized users can access the data. The proposed approach can be used for a wide range of IoV applications, including traffic management, collision avoidance, and route planning.
