Method for triggering network authentication and related devices

Abstract

The present application discloses a method for triggering network authentication and related devices, and belongs to the field of communication technologies. The method includes that: a first networkdevice receives a first message from a terminal, wherein the first message carries first identity information and identity information, the first identity information is obtained in a way that the terminal encrypts identity information of the permanent identity of the terminal based on a public key, and the identity information is used for identifying whether the first identity information is encrypted identity information and / or an encryption mode of the first identity information; the first network device sends a second message to a first security function entity based on the first identityinformation, and the second message is used to trigger authentication on the terminal, wherein the second message carries the identifier information. The present application provides a scheme for triggering an authentication process when encrypting identity information, and since the identity information sent by the terminal to the first network device is encrypted identity information, the identity information is prevented from being stolen or tampered during the transmission process so as to ensure the security of the terminal.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method for triggering network authentication and related equipment. Background technique [0002] Currently, a terminal can access a network through a 3GPP technology or a non-3GPP technology. Among them, when the terminal accesses the 5G network and registers for the first time, whether it is accessed through 3GPP technology or through non-3GPP technology, the terminal needs to send an attach message carrying permanent identity information to the core network equipment, so that the core network The device triggers an authentication process according to the attach message, thereby authenticating the terminal. [0003] In related technologies, when a terminal accesses a 5G network and registers for the first time, the terminal can connect to the core network through a next-generation base station (next generation node basestaion, gNB) or a non-3GPP interw...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem in the prior art that when the authentication process is triggered, the terminal provides the permanent identity to the AMF entity without encrypting the security of the terminal.
