A Secure Cloud Approach for Intelligent Transport Systems
Geoffrey Wilhelm, Marwane Ayaida, Hacène Fouchal · 2019
C-ITS (Cooperative Intelligent Transport Systems) are growing more than expected, they are an important part of smart cities. Connected vehicles is one of the most recent aspect of C-ITS. For these vehicles, usual communications could be ensured through wireless local area networks over ITS-G5 (based on WFI 802.11p). In smart cities, these interconnections form a Context Cloud. As a consequence a vehicle can access to information generated by any other C-ITS, no matter its location, as long as both are part of the Cloud. In this paper, we propose a secure Cloud environment for connected vehicles denoted VCDN, for Vehicular Central Data Networking, which exploits Information Centric Networking and Vehicular Cloud Computing paradigms to provide to vehicles the data generated in a Smart City. All the communications with the Cloud are authenticated messages and mainly Cooperative Awareness Messages (CAM). We have compared the performance of our solution to some other solutions, in particular REndez-vous NEtwork (RENE) and Named Data Networking (NDN). The results are promising since our solution is more efficient compared to these approaches in terms of network's overhead.
