Abstract: This application discloses a device authentication method and system, and an apparatus, and relates to the field of communication technologies, to perform authentication on a terminal device. The system includes a first analyzer, a second analyzer, and a network device. The first analyzer sends a first authentication model to the second analyzer. The network device sends a transmission feature of a first terminal device to the second analyzer. The second analyzer performs authentication on the first terminal device based on the transmission feature of the first terminal and the first authentication model.

Abstract: A device identification method, apparatus, and system are provided. A management device or a collection device first determines a network traffic feature of a to-be-identified device based on a first dataset. The first dataset includes a plurality of pieces of first data, and each piece of first data includes a data amount of a data packet that is of the to-be-identified device and that is collected within one first periodicity. Then, the management device or the collection device determines a device type of the to-be-identified device based on a device identification model and the network traffic feature of the to-be-identified device.

Abstract: A method, an apparatus, a system, a device, and a storage medium for implementing terminal verification are provided. In this method, a transmission feature of a terminal is reconstructed to verify the terminal. For example, if a difference between the transmission feature obtained through reconstruction and the transmission feature of the terminal is relatively large, it indicates that the transmission feature of the terminal is abnormal, and the terminal is an abnormal terminal. In this case, it is determined that the verification of the terminal fails.
