Embodiments of the present invention provide a key distribution and authentication method, device, and system. The key distribution and authentication method includes: the business center server receives the first key request message sent by the user management server, and according to the first key request message Generate the first key of the terminal device, and send the first key to the user management server; the user management server receives the first key of the terminal device sent by the business center server, and sends the first key of the terminal device to The terminal device is configured to enable the terminal device to perform mutual authentication with the network authentication server according to the first key. The service center server distributes different keys to each terminal device, and then each terminal device performs mutual authentication with the network authentication center based on its own key, and finally obtains the communication key between the terminal device and the functional network element, providing secure communication for the terminal device The channel establishment method has a wide range of applications.
Description
technical field [0001] The present invention relates to the communication field, in particular to a key distribution and authentication method, device and system. Background technique [0002] With the development of communication network technology, more and more devices have begun to join the network and send and receive data through the communication network, such as mobile phones, computers, drones and other Internet of Things devices. There are also more and more enterprises that realize the communication between the management center of the enterprise and the various intelligent devices that realize the business of the enterprise through the communication network, such as the electric power company, the water supply company or the heating company, etc. [0003] In order to ensure secure communication, smart devices and the network usually perform mutual authentication based on the root key to establish a secure channel. The root key used in the mutual authentication pr...
