Abstract: Securely communicating traffic between control units interconnected by a network. An electronic control unit (ECU) receives a signed manifest identifying public keys for a group of ECUs authorized to communicate over the network. The ECU performs an authentication exchange with the ECUs in the group. The authentication exchange uses public keys identified in the manifest. Based on the authentication exchange, the ECU distributes a group key to authenticated ones of the ECUs that communicate messages authenticated using the group key.
