摘要： A random number generation apparatus and method are provided, and may be applied to an electronic device that can be connected to an electric network, such as a green car, a smart home, or Internet of things. The random number generation apparatus (100) includes an ENF extractor (101), an entropy generation module (102), and an entropy pool (103), and may generate a true random number and a pseudo random number based on an ENF signal of an electric network (200) without using a hardware entropy source. This helps reduce manufacturing costs of the electronic device.

摘要： Embodiments of this application provide a vehicle-mounted device upgrade method and a related apparatus, applied to the field of vehicle information security. The method includes: An on-board unit of a vehicle processes a first data segment according to a first algorithm, to obtain a first check value, where the first data segment is any data segment in a plurality of data segments included in an upgrade file of a control unit used to upgrade the vehicle, and the first check value is sent to the control unit; and the vehicle-mounted device encrypts the first data segment by using a first key, to obtain a first encrypted segment, and sends the first encrypted segment to the control unit, so that the control unit stores, in the control unit, the first data segment obtained by decrypting the first encrypted segment by using the first key, where the first data segment is used by the control unit to form the upgrade file for upgrade. According to the embodiments of this application, security of the upgrade file in an in-vehicle transmission process can be effectively improved.

摘要： This application provides a data transmission method and an apparatus, applied to an intelligent vehicle, and a connected vehicle, to select an appropriate protection policy for to-be-transmitted data, and balance calculation resources of ECUs. The method includes: A first ECU obtains to-be-sent data. The first ECU determines a protection policy corresponding to the to-be-sent data from a plurality of protection policies, where the plurality of protection policies include a plurality of different encapsulation manners for the to-be-sent data, and the plurality of protection policies include at least two protection policies with different calculation amounts for processing the to-be-sent data. The first ECU encapsulates the to-be-sent data according to the protection policy corresponding to the to-be-sent data, to obtain an encapsulated packet. The first ECU sends the encapsulated packet to a second ECU, where the first ECU and the second ECU are any two ECUs in a vehicle.
