Abstract

The embodiment of the present invention provides a key distribution and authentication method, device and system, the method includes: the business center server receives the first key request message sent by the user management server, and generates the key request message of the user management server according to the first key request message. The first layer key, and send the first layer key to the user management server; the user management server generates the second layer key of the terminal device according to the first layer key, and sends the second layer key of the terminal device to The terminal device enables the terminal device to perform mutual authentication with the network authentication server according to the second layer key. The service center server and the user management server distribute 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, which is the terminal device A method for establishing a secure communication channel is provided, and 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...
