This chapter describes the initial working plan and the project carried out,
along with their respective analyses. The project focused on implementing a
cryptographic solution in the embedded system to ensure the authentication and
integrity of CAN messages. With the rise of the autonomous driving concept in the
automotive industry, there is a growing need for digital data processing and
communication both within the vehicle and with the external world, creating a
significant challenge to protect the data from cyber-attacks during communication.
Hence, cybersecurity has become an important topic in the automotive industry. This
project was carried out to ensure the security of data during communication on the
vehicle Controller Area Network (CAN) using message authentication. The chapter
concludes by highlighting the current technology's drawbacks and discussing potential
future improvements.
Keywords: Automotive industry, Cyber-attacks, CAN, Cybersecurity, MAC, Message authentication, Secure communication.
