Abstract

Reliable communication and safety in Vehicular Ad Hoc Networks (VANETs) depend on effective and secure authentication. This paper presents a new architecture that combines Roadside Units (RSUs) and SHA-256 with pseudonym-based authentication to overcome these issues. Utilizing the cryptographic power of SHA-256, the suggested approach creates a strong mechanism for managing and extracting secret keys. In order to facilitate safe communication via a blockchain-based consortium network in which RSUs serve as trustworthy nodes, a distinct pseudonym is provided at vehicle registration. In order to guarantee data integrity and message validity, these RSUs work together to produce and distribute cryptographic keys. While the blockchain ledger preserves an unchangeable record of authentication events, improving transparency and traceability, the pseudonym method improves privacy by routinely altering vehicle identities as well. Even if this decentralized architecture reduces single points of failure, there is still room for improvement in terms of scalability and latency. By improving VANET security, the suggested solution creates a foundation for safer and more effective vehicular communication.
