However, traditional authentication schemes exhibit significant limitations in privacy protection, low latency, and multi-domain collaborative authentication, particularly in high-speed scenarios where vehicles frequently switch domains. Additionally, existing solutions relying on centralized authentication architectures are vulnerable to single points of failure, further exacerbating security risks.To address these challenges, this paper proposes a Blockchain-Assisted Traceable Cross-Domain Anonymous Authentication Mechanism (BTCAA), aimed at providing secure and efficient authentication for high-speed moving vehicles accessing VFS. BTCAA designs a flexible authentication process that allows vehicles to dynamically adjust authentication procedures based on their driving routes and introduces anonymity to protect user privacy. The mechanism adopts a lightweight design to reduce authentication overhead while supporting identity traceability, ensuring the ability to verify vehicle identities in dispute scenarios without compromising anonymity. The decentralized architecture eliminates the risk of single points of failure, enhancing system security. Security analysis confirms that BTCAA effectively ensures privacy protection, identity traceability, message integrity, and confidentiality. Performance evaluations further demonstrate its high practicality and efficiency while maintaining robust security and privacy protection.Keyphrases: anonymous, blockchain, cross domain authentication, vehicle fog services In: Akira Yamada, Huy Kang Kim, Yujue Wang and Tung-Tso Tsai (editors).
