General Information

Serial Data Authentication Configuration (or Key Provisioning) enables secure communication between control modules over different communication channels. This is critical for maintaining communication security. It ensures sensitive data exchanged between control modules is encrypted, preventing tampering and unauthorized access.

• During the process, control module data is retrieved from the vehicle to generate unique cryptographic keys.
• These keys are then written to each control module, allowing secure communication between control modules.
• In the case of control module replacement, re-running the configuration is required to introduce the new control module to the network; otherwise, communication will fail due to unrecognized messages.
