Security on in-vehicle communication protocols: Issues, challenges, and future research directions

The automotive industry has represented an important sector of industrial development worldwide. With technology growth, vehicles have been equipped with various devices that allow them to perform different functions, increase autonomy level, and give drivers greater confidence and comfort. In this sense, data security is a fundamental feature since access to car functionalities needs to be protected from outsiders, only allowing access to authorized users. It means to guarantee data security through communication buses even when connecting from external devices. Therefore, it is necessary to design new security techniques that increase the confidentiality and improve authentication in new vehicles.
