Abstract: To address the reliance on traditional PKI for establishing trust between entities in vehicular named data networking (VNDN), we propose a hierarchical blockchain-based self-sovereign identity (SSI) scheme for decentralised vehicular named data networking (DVNDN). In our scheme, RSUs and vehicles are registered under supervision of a trusted authority (TA). Then, a committee consisted of RSUs selected is used to manage decentralised identifiers (DIDs) and verifiable credentials (VCs) for vehicle. This approach enables VC-based trust establishment without third-party anchors as in PKI. The proposed solution adopts signature of knowledge (SoK) and non-interactive zero-knowledge proofs (NIZKs) to protect privacy during issuance, presentation, and verification of VC, with the ZoKrates toolkit employed for generating NIZK proofs and enabling on-chain verification. Our security analysis demonstrates that the proposed scheme meets security requirements. Experimental results show feasibility, reliability, and effectiveness of our scheme by applying the Ethereum-based platform on NDN into the vehicular network.
