Abstract
Disclosed are techniques for securing electronic control units (ECUs) in a vehicle while allowing secure repairing of the ECUs. A method of repairing a vehicle includes disabling message authentication in secure communication between any two ECUs in a plurality of ECUs on the vehicle, detecting a first ECU that has been changed based on detecting an absence of a valid security key on the first ECU, verifying that a digital certificate associated with the first ECU is a valid certificate, generating one or more security keys for secure communication between the first ECU and a set of ECUs in the plurality of ECUs, provisioning the one or more security keys to the first ECU and the set of ECUs, and enabling the message authentication in secure communication between any two ECUs of the plurality of ECUs.
