【Abstract】The proliferation of intelligent transportation technology has led to an increased frequency of communication between vehicles. However, the openness of the Internet of Vehicles and wireless communication has introduced substantial privacy and security concerns, necessitating the adoption of identity authentication technology to ensure secure vehicle-to-vehicle communication. In response to the challenges posed by single point of failure and high computational costs in traditional centralized identity authentication schemes, this study proposes a blockchain-based batch authentication scheme for the Internet of Vehicles BBASV. By leveraging a non-pairing certificateless mechanism, the BBASV scheme effectively addresses these limitations, reducing the computational complexity and network traffic in the authentication process, thereby enabling efficient batch authentication. Additionally, identity-based prefix-key encryption is utilized to preserve the privacy of vehicle identities during proxy vehicle broadcasting. Moreover, the proxy vehicle leverages signature fusion technology to perform batch authentication on neighboring vehicles, alleviating the authentication burden on roadside units. The effectiveness of the BBASV scheme is rigorously evaluated through theoretical analysis and empirical experimentation, demonstrating its resilience against various security threats, including DoS attacks, man-in-the-middle attacks, and simulated attacks. Furthermore, the scheme exhibits favorable attributes such as low computational requirements and network traffic, rendering it a promising solution for ensuring secure and privacy-preserving communication within the Internet of Vehicles domain.
