摘要： Embodiments of the present invention disclose a device upgrade method and a related device, which may be specifically applied to an intelligent vehicle and a driverless vehicle, to ensure upgrade security of a vehicle-mounted device in the vehicle. The method includes: A control device receives first upgrade file data sent by a communications device, where the first upgrade file data is upgrade file data generated after the communications device performs first security processing on an upgrade file by using a first key. The control device performs second security processing on the first upgrade file data by using a second key, to generate second upgrade file data, and sends the second upgrade file data to a to-be-upgraded device. The to-be-upgraded device receives the second upgrade file data, performs security verification on the second upgrade file data by using a corresponding verification key, and performs upgrade by using the upgrade file if the verification succeeds. This application may be applied to a plurality of technical fields such as a smart home and smart driving, to ensure secure and efficient upgrade of a home device or a vehicle-mounted device.

摘要： This application provides a method for identifying an abnormal message, a method and an apparatus for training an abnormal message identification model. The methods in the embodiments of this application are applicable to the field of automobiles or ships. The method for identifying an abnormal message includes: A security enforcement unit SEU receives a first message, and determines a first difference value between a feature value of the first message and a feature value of a second message, where the second message is a message that is received before the first message is received; the SEU determines, from a plurality of preset difference classes, a difference class corresponding to the first difference value, where different difference classes in the plurality of difference classes correspond to different value ranges of a difference value; and the SEU inputs an identifier of the difference class corresponding to the first difference value into a pre-stored abnormal message identification model, to determine whether the first message is the abnormal message or a non-abnormal message. This helps improve accuracy of identifying the abnormal message based on the abnormal message identification model.

摘要： A fault diagnosis method, an apparatus, and a vehicle are provided, to resolve a prior-art problem that an unauthorized diagnostic tester interferes with a vehicle. The method may be applied to a vehicle. The vehicle includes an ECU and a gateway. The gateway is configured to manage the ECU. The method includes: The gateway performs authentication on a diagnostic tester. If the authentication succeeds, the gateway generates a first shared key, and sends the first shared key to the ECU. The first shared key is a key shared between the ECU and the diagnostic tester. The ECU encrypts to-be-transmitted diagnostic data by using the first shared key, and sends encrypted diagnostic data to the diagnostic apparatus. The gateway performs authentication on the diagnostic tester. This is conducive to avoiding interference of an unauthorized diagnostic tester on the vehicle, and is also conducive to reducing overheads of the ECUs. Further, it is conducive to improving security of the diagnostic data transmitted by the ECU to the diagnostic tester.
