Static User Terminal Authentication via EAP Certificate Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods for static user terminals in broadband networks lack security and mobility, particularly in wireless LAN scenarios, where circuit authentication is complex and insecure, leading to difficulties in air interface data security and limited user mobility.
Innovation Solution
Implementing an Extensible Authentication Protocol (EAP) authentication method for static user terminals, which involves sending an identity request message, receiving a response, and performing EAP authentication, followed by negotiating a key for air interface data message interaction using a pair-wise master key, and interacting with an AAA server for secure network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If circuit authentication is used for static user terminals, then user identity can be verified, but security is poor and mobility is limited
Solution Approach 1:
The patent changes the authentication parameter from circuit-based identification to certificate-based cryptographic verification. By transforming the authentication mechanism from checking circuit parameters (MAC address, IP address) to verifying digital certificates and cryptographic signatures, the system achieves both high security and user mobility without being bound to specific circuit configurations.
2Ease of operation
If manual network configuration is used for static users, then network parameters can be set, but maintenance complexity increases
Solution Approach 1:
The patent implements self-service authentication where user terminals automatically perform certificate verification and authentication procedures without requiring manual configuration of network parameters. The terminal autonomously manages its own authentication credentials and completes the verification process with the network device, eliminating the need for operators to manually configure MAC addresses, IP addresses, and other network parameters.
3Reliability
If traditional authentication methods are used, then static users can access network, but air interface data security cannot be ensured
Solution Approach 1:
The patent introduces cryptographic certificates and cryptographic verification mechanisms as intermediaries between the user terminal and the network. Instead of direct trust relationships, the system uses digitally signed certificates as mediators that provide cryptographic proof of identity and authorization, ensuring air interface data security through mathematical verification rather than simple parameter matching.
