Abstract

We propose a method to include security and reliability to the messages sent over the CAN bus. Our approach adheres to CAN standard ISO 11898-1. A reliable PUF response is used in key generation to create a unique shared AES-256 key between each ECU, allowing for all message paths to be encrypted. In addition, an HMAC system with a counter is implemented to help protect against replay attacks and message tampering within the network.
