Dynamic Device Authentication Table for Terminal Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in providing accurate and reliable device authentication for terminal devices in the context of internet technologies, particularly in ensuring security and reliability of communication between terminal devices and servers.
Innovation Solution
A device authentication method that involves receiving and parsing authentication requests from terminal devices using a preset device table, where physical code information is matched against preset terminal device codes, with options to add new codes if the threshold is not reached, and performing identity authentication using feature extraction models and databases.

Engineering Contradiction Analysis
1Reliability
If device authentication is performed using a preset device table with fixed threshold, then security and reliability of communication are improved, but device complexity and operational difficulty increase when new devices need to be added
Solution Approach 1:
The device table is designed with dynamic capacity expansion capability. When the number of authenticated devices reaches the preset threshold, the system automatically allows adding new device codes, transforming the static threshold into a dynamic parameter that adapts to actual authentication needs, thereby resolving the contradiction between maintaining security through fixed thresholds and accommodating new devices.
Solution Approach 2:
The system pre-sets a threshold value for the device table capacity in advance. This preliminary configuration allows the system to automatically manage device additions without requiring manual intervention or complex administrative operations, simplifying the management process while maintaining authentication reliability.
2Measurement precision
If authentication requests from multiple terminal devices are processed sequentially, then authentication accuracy is maintained, but authentication efficiency and user experience deteriorate
Solution Approach 1:
The authentication processing is segmented into independent parallel tasks. Each authentication request is handled as an independent unit that can be processed concurrently with other requests, allowing the system to maintain accurate authentication checking while significantly improving overall processing efficiency through parallel execution.
Solution Approach 2:
The system implements continuous authentication processing by handling multiple device authentication requests simultaneously without interruption. This continuous parallel processing maintains the accuracy of individual authentication checks while maximizing throughput and efficiency, preventing idle time between sequential operations.

AI summary
Disclosed is a device authentication method used in a server, comprising: (S11) receiving a certification request sent by at least one terminal device; (S12) parsing the certification request so as to perform authentication on physical code information of the terminal device according to a preset device table; (S13) in a situation where the physical code information of the terminal device matches a preset terminal device code, determining that the terminal device passes authentication; (S14) in a situation where the physical code information of the terminal device does not match any preset terminal device code in the preset device table and the total number of preset terminal device codes in the preset device table has not reached a threshold, in response to an add-to-device table operation, adding the physical code information of the terminal device to the preset device table and determining that the terminal device passes authentication.
