Abstract: Various techniques related to authenticating and verifying the integrity of data received by a computer system from an external source (such as a sensor) are disclosed. Hardware circuits are disclosed that, along with the computer processor, allow for error-checking and authentication of data received by the computer system. For instance, the hardware circuits may generate a separate authentication code that can be compared to the authentication code in the data itself to determine whether or not the message is authentic and whether or not there is an error in the data. The disclosed techniques reduce the processing requirements of a computer system and can be implemented using simple hardware circuit designs.

Abstract: The present disclosure generally relates to methods for sending event notifications. In some examples, a controller periodically sends messages concerning a status of an event corresponding to the controller. In some examples, at a first time while periodically sending the messages and in accordance with a determination that the status of the event has changed, the controller sends a message concerning data other than the status of the event. In some examples, at the first time while periodically sending the messages and in accordance with a determination that the status of the event has not changed, the controller continues to periodically send the messages without sending the message concerning data other than the status of the event.

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.
