Research on Identity Authentication Technology of Vehicle Networking Users Based on Commercial Password

A solution anchored in commercial cryptography is proposed, tackling the identity authentication conundrum in the Internet of Vehicles (IoV) milieu. This paper introduces blockchain and an Attribute-Based Encryption (ABE) algorithm to bolster the security and efficiency of authentication processes. Initially, the multifaceted challenges of user identity authentication in vehicle networking are analyzed, encompassing security, real-time responsiveness, and scalability. Subsequently, a novel commercial password-based authentication model is constructed, harnessing blockchain technology to ensure authentication information remains immutable and transparent, while employing ABE to achieve fine-grained access control and robust data protection. To substantiate the model’s validity, the research team developed a sophisticated computer simulation system, conducting simulations across a diverse array of vehicle networking scenarios. Simulation outcomes affirm the model’s capability to effectively thwart various network attacks, maintaining low computing and communication overheads, and satisfying the stringent identity authentication requirements in the networked vehicle environment. This innovative approach promises enhanced security, efficiency, and reliability in vehicular communication networks.
