Core Network Authentication via Data Network Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication methods in network communications leak user identity information, compromising privacy security due to the transmission of sensitive data across multiple devices.
Innovation Solution
An authentication method where a core network device sends an authentication request message to a data network device with first information that indicates user identity, ensuring this information remains invisible to other devices, thereby preventing leakage during transmission, and includes mechanisms to verify the authenticity of the user identity information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user identity information is transmitted to core network device for authentication, then authentication can be performed, but user privacy security deteriorates due to information leakage
Solution Approach 1:
The patent introduces a data network device as an intermediary between the terminal device and core network device. The data network device receives user identity information from the terminal device, performs authentication, and returns authentication results without exposing the user identity information to the core network device or access network device. This intermediary structure enables authentication while preventing privacy leakage through information isolation.
2Reliability
If user identity information is transmitted across multiple devices, then authentication can be completed, but signaling overhead increases
Solution Approach 1:
The patent extracts the authentication function from the core network device and relocates it to the data network device. By taking out the authentication capability from the central core network device and placing it at the edge data network device, the system reduces the amount of user identity information that needs to be transmitted through the core network, thereby reducing signaling overhead while maintaining authentication functionality.
Data Source
AI summary
An authentication method, apparatus, and device. The method includes sending, by a core network device, an authentication request message of a user to a data network device, where the authentication request message requests that the data network device perform identity authentication on the user, and receiving, by the core network device, an authentication response message sent by the data network device, where the authentication response message comprises first information, and the first information indicates user identity information of the user.
