Blockchain-based Self-Sovereign Identity Solution for Vehicular Networks

Identity and access management frameworks address data governance and system access rights for users, organizations, and vendors. Emerging identity management models such as Self-Sovereign Identity (SSI) that is based on Distributed Ledger Technology (DLT) technology, have emerged to address the challenges associated with centralized authority. The main goal of SSI is to help users self-manage their data shared with services. In this paper, we explore a possible application of the SSI concept to vehicular networks. We propose a new methodology, that is alternative to the conventional blockchain-based SSI, which ensures confidentiality, authentication, and integrity of vehicle users identity and their data. At the end of the paper, we also compare SSI-based and Non-fungible token (NFT)-based blockchain solutions, the challenges and future directions of SSI solutions in the context of vehicular networks.
