Abstract
In the evolving automotive sector, secure communication within
Controller Area Network (CAN) systems is crucial. This thesis examines and
enhances a HMAC-based communication scheme, focusing on counter
synchronization in Electronic Control Units (ECUs). By identifying and
addressing key limitations, we propose effective improvements, thus elevating
the security of CAN-based systems.
With the advancement of automotive technologies, securing
communication in CAN-based systems is essential. This research identifies
vulnerabilities in an existing HMAC-based scheme, particularly in counter
synchronization, and proposes robust solutions for these challenges.
The study highlights vulnerabilities like counter overflow and memory
errors in the original scheme. Solutions include a Special Initialization Message
(SIM) for counter value clarity and a redundancy mechanism for memory error
prevention. These enhancements were rigorously tested against real-world use
cases, demonstrating improved security and reliability.
This research contributes significantly to secure automotive
communication protocols. The proposed solutions, tested and validated, pave
the way for stronger, more reliable automotive systems. Future work may
explore extending these solutions to diverse automotive environments and
integrating with new communication standards.
