Abstract
Disclosed are techniques for securing electronic control units (ECUs) in a vehicle. A security platform for a vehicle includes a key distribution center (KDC) for the vehicle. The KDC is configured to verify that a digital certificate associated with a first electronic control unit (ECU) on the vehicle is a valid certificate, where the digital certificate indicates a first security level of the first ECU. The KDC is configured to generate, based on the first security level of the first ECU, one or more security keys for secure communication between the first ECU and a set of ECUs on the vehicle, and provision the one or more security keys to the first ECU and the set of ECUs. In some embodiments, the KDC uses the provisioned keys to authenticate each ECU when the vehicle is powered up.
