摘要： This application discloses a device management method, system, and apparatus, to implement automatic management on a device, thereby effectively protecting data privacy and security of the device. The method includes: A second device sends an identity file to a first access control node, to indicate the first access control node to store the identity file in a file system, where the identity file includes identity information of a first device and a public key of the second device. The second device receives a first identifier sent by the first access control node. The first identifier is used to read the identity file from the file system. The first identifier is generated by the file system after the first access control node sends the identity file to the file system. After verification is performed on the second device and information about a device associated with the first device in association information and succeeds, the first access control node sends the identity file to the file system. The association information is stored in a database node and a blockchain.

摘要： This application provides an in-vehicle gateway communication method, an in-vehicle gateway, and an intelligent vehicle. When receiving a first message from a first in-vehicle device, the in-vehicle gateway identifies identification information in the first message, and matches the identification information with preset identification information stored in the in-vehicle gateway, and only when the matching succeeds, the in-vehicle gateway sends a second message, to indicate, by using the second message, a second in-vehicle device to perform a target operation. However, when the identification information in the first message cannot match the preset identification information stored in the gateway, the in-vehicle gateway does not send the second information to control the second in-vehicle device to perform the target operation. Therefore, in this application, identification information of a first message is set in an in-vehicle gateway of a vehicle. This reduces a security threat to an in-vehicle network, and improves security performance of an in-vehicle network of a vehicle.
