Key distribution and authentication methods, devices and systems

Abstract

Embodiments of the invention provide key distribution and authentication methods, devices and systems. The methods comprise the following steps that a business center server receives a first key request message sent by a user management server, generates a first-layer key of the user management server according to the first key request message and sends the first-layer key to the user management server; and the user management server generates a second-layer key of a terminal device according to the first-layer key and sends the second-layer key of the terminal device to the terminal device in order to make the terminal device and a network authentication server carry out mutual authentication according to the second-layer key. The business center server and the user management server distribute the different keys to each terminal device, each terminal device carries out mutual authentication with the network authentication center based on the respective key, and a communication key of the terminal device and a function network element is finally obtained, a method for establishing a safety communication channel is provided for the terminal device, and the application range is wide.

AI Technical Summary

Benefits of technology

This technology allows users or customers (called clients) access their own device's data through an internet connection without having to remember multiple passwords on each phone they are accessing it from one country where another person has established upgrades with mobile phones. It simplifies this process because instead of requiring all new ones at once, only necessary parts like those used during previous versions have been generated.

Problems solved by technology

This patents discuss how current techniques for securizing wireless networks involve creation of new keys from scratch when upgraded into older ones without supporting any specific fuzzy identification numbers called UICCs. These technical problem addressed in this patented solution can result in poor security measures being established due to lack of knowledge about what kind of equipment they've been connected upstream during their lifetime.
