Abstract

The invention discloses a device credential distribution method, a device credential distribution system, user equipment and a management entity. The method includes the following steps that: user equipment (UE) sends IOT device credential request information to an operator user subscription authentication management entity; the user subscription authentication management entity generates corresponding credential information according to IOT device identity information in the received credential request information, wherein the credential information contains an IMSI and an authentication keyK; after receiving the credential information, the UE sends the credential information to a corresponding IOT device; and the IOT device is attached to a mobile communication system according to the credential information. With the device credential distribution method, the device credential distribution system, the user equipment and the management entity provided by the technical schemes of thepresent invention adopted, an asymmetric key system is not required to be supported, only a symmetric key system is needed, and therefore, a device credential distribution process is simplified, and system performance can be improved.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, in particular to a device certificate distribution method and system, user equipment and a management entity. Background technique [0002] Large-scale machine connection is one of the typical application scenarios of 5G systems. In large-scale machine connection application scenarios, it is difficult to pre-configure Internet of Things (IOT, Internet Of Things) terminal devices for network access and IoT services before deployment. credential information. In addition, during the use of IoT terminal devices, due to user needs, it may be necessary to change operators or IoT services, which requires remote distribution of credentials for IoT devices. In the 5G system, the IOT devices are usually managed by the user, and the user realizes the management of the IOT device through the short-distance communication connection between the UE and the IOT device. Therefore, the current crede...
