Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is performed by wireless access point devices, then authentication can be completed, but authentication time is prolonged and network performance degrades
Solution Approach 1:
The patent introduces a cloud server as an intermediary between the wireless terminal and the access point device. The cloud server receives authentication information from the access point, performs verification using stored verification keys, and returns results to the access point. This mediator approach transfers the computationally intensive authentication verification from the access point to the cloud server, resolving the contradiction by maintaining authentication reliability while reducing access point processing time and network degradation.
2Reliability
If authentication verification is performed by wireless access point devices, then authentication can be completed, but performance pressure on access point devices increases
Solution Approach 1:
The cloud server serves as an intermediary that handles the performance-intensive authentication verification task. The access point device only performs lightweight information collection and transmission, while the cloud server performs the computationally intensive verification using stored verification keys. This division of labor significantly reduces the performance pressure on access point devices while maintaining authentication reliability.
Solution Approach 2:
The patent implements a verification key distribution mechanism where verification keys are stored in the cloud server and copied to the access point device when needed. This allows the access point to perform authentication without maintaining large key databases locally, reducing its storage and processing requirements while ensuring authentication can still be completed reliably.
3Reliability
If existing authentication processes are used in enterprise wireless networks, then authentication can be performed, but authentication efficiency is low
Solution Approach 1:
The cloud server acts as an intermediary that significantly improves authentication efficiency by handling verification operations remotely. The access point device simply collects authentication information and transmits it to the cloud server, which performs rapid verification using pre-stored verification keys and returns results quickly. This mediator architecture eliminates the bottleneck of local verification at the access point, thereby improving overall authentication efficiency while maintaining full authentication functionality.
Solution Approach 2:
The patent implements preliminary action by pre-storing verification keys in the cloud server before authentication is needed. When authentication occurs, the cloud server can immediately retrieve and use the appropriate verification key without performing complex key generation or search operations in real-time. This preliminary preparation significantly speeds up the authentication process and improves productivity while ensuring reliable authentication functionality.

AI summary
A cloud server receives information to be authenticated sent by a wireless access point device. The information to be authenticated contains verification information generated by a terminal to be authenticated. The terminal is a wireless terminal provided by the wireless access point device for accessing a wireless local area network. The cloud server determines that it locally stores a verification key that matches the terminal. The cloud server obtains the locally stored verification key and performs verification on the verification information according to the verification key. When the verification on the verification information succeeds, the cloud server the verification key to the wireless access point device so that the wireless access point device associatively stores the verification key with a terminal identifier of the terminal and completes authentication on the terminal according to the verification key.
