Decentralized Identities for Enhanced Security in Vehicle-to-Everything (V2X)

The rise of Vehicle-to-Everything (V2X) communication in Intelligent Transportation Systems (ITS) enhances road safety and traffic management but introduces security vulnerabilities like impersonation and data tampering. Traditional identity management systems such as Public Key Infrastructure (PKI) are limited by their reliance on centralized authorities. This paper proposes a decentralized framework using Decentralized Identifiers (DIDs), Verifiable Credentials (VCs), and Distributed Ledger Technology (DLT), integrating Zero-Knowledge Proofs (ZKPs) to secure identity management in V2X systems. The proposed framework achieves robust authentication, mitigates centralization risks, and enables privacy-preserving mechanisms, demonstrating enhanced scalability and resilience against attacks in V2X communication.
