Advanced wireless communication and artificial intelligence technologies are significantly facilitating the deployment of driverless taxis (DTs). To ensure high-quality of DT services, data sharing among DTs is essential during service provision. However, at least three key challenges are then raised in terms of security and privacy: 1) guaranteeing data authenticity with traceability; 2) enabling flexible data authorization and preserving privacy amid complex data ownership; and 3) protecting DT privacy under frequent data sharing. Most existing works address only one aspect, such as data authenticity, privacy preservation, or single-entity authorization. To address these challenges, we propose a novelMulti-authorized,Privacy-protected, andTraceableDataSharing (MPTDS) scheme for DTs. Firstly, MPTDS upholds data privacy preservation by designing the data sharing credential for each DT and the data access credential for each service provider. Data sharing credential also ensures anonymity and unlinkability of DTs. Secondly, MPTDS ensures data integrity and origin authentication by designing the credential-based authentication technique for DT, which also enables the traceability. Additionally, MPTDS facilitates the data multi-authorization by designing the data sharing credential multi-party issuance technique without sacrificing the non-frameabiltiy. We conduct security analyses and performance evaluations to validate the security properties and practicality of MPTDS.
