  This paper introduces a novel blockchain-enabled authentication and
communications network for scalable Internet of Vehicles, which aims to bolster
security and confidentiality, diminish communications latency, and reduce
dependence on centralised infrastructures like Certificate Authorities and
Public Key Infrastructures by leveraging Blockchain-enabled Domain Name
Services and Blockchain-enabled Mutual Authentication. The proposed network is
structured into a primary layer, consisting of Road Side Units and edge servers
as servers of Blockchain-enabled Domain Name Services for managing
inter-vehicle communications identities, and a sub-layer within each vehicle
for intra-vehicle communications via the Blockchain-enabled Mutual
Authentication Protocol. This design facilitates secure connections across
vehicles by coordinating between the layers, significantly improving
communications security and efficiency. This study also evaluates Road Side
Unit availability against the random distribution of Road Side Units along the
route of different vehicles. The proposed model presents a novel pathway
towards a decentralised, secure, and efficient Internet of Vehicles ecosystem,
contributing to the advancement of autonomous and trustworthy vehicular
networks.
