A Novel Embedded Platform for Secure and Privacy-Concerned Cross-Domain Service Access

Connected driving is a hot topic in the automotive industry and a leverage to push new Mobility as a Service (MaaS) methodologies, making vehicles an essential part of the Internet of Things (IoT). However, these new technologies often lead to security risks and privacy concerns, especially due to the increasing number of datasets exchanged between vehicles, drivers, and local infrastructure. Furthermore, the possibilities for vehicles to access heterogeneous services offered by different service providers are often limited due to rigid system boundaries. In this paper we present a novel federated service management concept for increased interoperability across distinct services in the field of Smart Mobility and Smart Cities. Our approach provides secure authentication and authorization between cars, their drivers, and other information systems, while retraining the level of privacy according to the users' preferences. The scalability and dynamic configurability of the solution and the elaborated proof-of-concept will set it apart from application-centered gateways to an embedded generic platform by virtue of its modular software design.
