Secure Communication Over In-Vehicle Network Using Message Authentication

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.
