Problems solved by technology

[0004] For scenarios such as terminal device update, the MUD file and the corresponding MUD URL both change, which requires that the MUD URL in the terminal device is also updated to the changed MUD URL. However, in the terminal device, the content in the certificate cannot Changes are made, that is, the MUD URL carried in the certificate cannot be updated flexibly, resulting in the inability of the network device to accurately obtain the updated MUD file, thus making it impossible to effectively constrain the current terminal device

Abstract

The embodiment of the invention discloses a method and equipment for obtaining a manufacturer use instruction MUD file. MUD control management equipment takes an MUD URL which is verified to be legal as a credible basis, and when terminal equipment is currently updated, the MUD control management equipment obtains a new MUD file based on a new MUD URL which meets a matching condition with the credible MUD URL; or the fixed attribute information of the legal MUD URL is used as a credible basis by the MUD control management equipment, and when the terminal equipment is currently updated, the updated MUD URL and the new MUD file are obtained by the MUD control management equipment based on the credible fixed attribute information and the newly received variable attribute information. Therefore, the method and the equipment can be suitable for a terminal equipment updating scene, and it is possible to flexibly, safely and effectively acquire the corresponding MUD file after the terminal equipment is updated by the MUD control management equipment.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for obtaining a manufacturer usage description (English: Manufacturer Usage Description, MUD for short) file. Background technique [0002] With the continuous improvement of digitalization and intelligence, more and more terminal devices appear in network scenarios, for example, more and more terminal devices (such as : printers, cameras, smart LED lights, conference room projection equipment, etc.). In order to restrict various terminal devices, the manufacturer of the terminal device will generate a MUD file that includes information describing the device type of the terminal device, network access rights, etc., and the network device connected to the terminal device when it accesses the network can apply the MUD file Make corresponding constraints on the terminal equipment. [0003] At present, the manufacturer of the terminal devi...
