Blockchain-Based Lightweight Authentication Protocol for Next-Generation Trustworthy Internet of Vehicles Communication

Intelligent transport systems (ITSs) aim to improve the performance of vehicular ad hoc networks (VANETs). It provides new opportunities for the Internet of Vehicle (IoVs) environment but poses some security concerns, especially concerning the Vehicle-to-Vehicle secure communication connection. The advent of the Next Generation technology for Internet of Vehicles (IOVs) secure communication has greatly benefited mobile networks. While 5G IoVs has many privacy and security challenges, several must be addressed. The confidentiality and privacy of data transmitted between vehicles, roadside units (RSU), and control rooms is a critical issue that must be addressed effectively. Blockchain technology presents a potential solution for securing the IOVs because of its decentralization, stability, and transaction tracking capabilities. To overcome these issues, this paper introduces BLAP-IOVs, a Blockchain-based Lightweight Authentication Protocol for generating Trustworthy IOVs communication. Comprehensive analysis and simulation results verify that the proposed BLAP-IOVs approach is efficient for secure information transmission in IOVs. Experimental results demonstrate that the proposed BLAP-IOVs approach achieves high success communication rates with acceptable vehicle-to-vehicle (V2V) loss and computation overhead. BLAP-IOVs suggest using Blockchain to improve Security, trust, and collaboration.
