Abstract:

A method of communicating via a vehicle communication network includes providing an electronic control unit (ECU), the ECU including a main processing unit and a security processing unit, the security processing unit including a symmetric security key, attempting a secure boot of the main processing unit, providing use of the symmetric security key to the main processing unit if the secure boot of the main processing unit is successful, preventing use of the symmetric security key by the main processing unit if the secure boot of the main processing unit is not successful, conducting, via an attestation processing unit, a remote attestation of the main processing unit, and determining, via the attestation processing unit, whether the secure boot of the main processing unit was successful according to the remote attestation.
