We are living today the so called "Digital Revolution" that started 50 years ago. Younger generations are forcing the transportation industry to move towards social, connected, environment-friendly, assisted means of transport. The intelligent, fully-digitized autonomous vehicle is an evolutionary process that starts right into the connected vehicle. But such complex system is becoming more and more vulnerable to external cyber attacks as it increases its connectivity capabilities. However, the Groupe Renault, the world's leading French vehicle-manufacturer, is ready to confront these challenges. This project focuses on the design, implementation and automation of a variety of test cases aiming to partially validate the embedded software running on the IVC, the on-board modem that provides Internet accessibility to connected vehicles. Both cybersecurity and performance aspects will be considered, a series of results will be presented and analyzed, and some relevant conclusions will be eventually drawn. This project is part of the Dual Degree Program arranged between the UPC-ETSETB --based in Barcelona and specialized in Telecommunications, and ISAE-SUPAERO --based in Toulouse and specialized in Aeronautics and Space, two of the best European Engineering Schools. It was carried out at Renault Software Labs, a fully-owned subsidiary of the Groupe Renault, based in Toulouse, France.
