The blockchain technology has recently attracted increasing interests in a wide range of use-cases. Among those, the management of vehicles' data and life cycle over a blockchain has sparked various research initiatives on a global scale, with the promise to prevent automobile frauds and to enable more collaborations between the involved stakeholders. In this paper, we investigate the problem of securing and sharing vehicles' data over a consortium blockchain, and we describe the architecture of the implemented proof-of-concept. Then, we introduce a novel hybrid cryptographic protocol to secure the access to vehicles' data between the involved stakeholders. Finally, we discuss the lessons learned acquired from the preliminary trials and we highlight the future research challenges and opportunities.
