iBCTrans: A Practical Blockchain-Based Framework for Cellular Vehicular -To -Everything Networks

As Intelligent Transportation Systems and Connected Vehicles become increasingly prevalent, establishing secure, efficient, and scalable communication infrastructures has become imperative. This paper introduces iBCTrans, a novel framework designed specifically for Cellular Vehicularto-Everything (C-V2X) Networks, leveraging a blockchain-based approach to address the challenges in vehicular communication scenarios. iBCTrans integrates blockchain technology with SelfSovereign Identity (551) principles and Decentralized Identifiers (DIDs) to facilitate secure and trustworthy V2X applications among vehicles, infrastructure, and networks. In this framework, vehicles can authenticate their identities in a secure and privacy-preserving manner, ensuring the integrity and reliability of the communication. A detailed overview of the iBCTrans architecture, components, protocols, and workflows is presented and potential applications in various vehicular communication scenarios are discussed. The proposed iBCTrans framework aims to provide a robust solution for the emerging demands of V2X communications, paving the way for the next generation of intelligent vehicular networks.
