The method includes: a service center server distributes different keys to terminal devices, and then the terminal devices perform mutual authentication with the network authentication server based on respective keys and finally obtain communication keys for communication between the terminal devices and a functional network element. This provides a method for establishing a secure communication channel for the terminal device, having a broad application range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Key distribution and authentication method and system, and apparatus","description":"This application provides a key distribution and authentication method, system, and an apparatus.
