Certificate Application via Gateway Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The continuous upgrade of browser technologies and diversity of browsers complicates the stability and compatibility of data transmission channels between local devices and browsers, necessitating browser-dependent controls for digital certificate validation in network environments, which affects the reliability of interaction information in data service scenarios.
Innovation Solution
Implementing a certificate application method and apparatus that uses data transmission channels between terminal devices and gateways, independent of browser controls, by establishing channels based on subscription topic names, allowing decoupling from browser compatibility and enabling reliable digital certificate management and validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If browser controls are used for digital certificate validation, then digital certificate management can be implemented, but the stability and compatibility of data transmission channels are affected due to browser technology upgrades and diversity
Solution Approach 1:
The patent introduces a gateway as an intermediary component between the terminal device and the certificate server. The gateway establishes a dedicated data transmission channel that mediates all certificate-related communications, isolating the system from direct browser dependency. This intermediary structure allows the certificate validation process to proceed through a stable, controlled channel while the browser merely initiates the process, thus resolving the contradiction between maintaining browser compatibility and ensuring transmission stability.
2Ease of operation
If browser-dependent controls are used for certificate validation, then digital certificate functionality is achieved, but the complexity of maintaining compatibility across diverse browsers increases
Solution Approach 1:
The patent extracts the certificate validation logic from the browser environment and relocates it to a gateway-based architecture. The browser's role is reduced to merely triggering the certificate application process, while the actual validation, channel establishment, and data transmission are handled by the gateway and certificate server. This extraction eliminates the need to manage browser-specific compatibility issues while maintaining ease of operation for users.
3Reliability
If a dedicated data transmission channel independent of browser controls is established, then reliability of data interaction information is enhanced, but the complexity of establishing and managing the channel increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing the data transmission channel between the terminal device and the gateway before certificate validation begins. The gateway proactively creates and maintains this dedicated channel, and the terminal device subscribes to relevant topics in advance. This preliminary setup ensures that when certificate validation is needed, a reliable communication path is already in place, eliminating the need to manage channel complexity during the actual validation process.
Data Source
AI summary
Implementations of this disclosure provide for certificate application operations. An example method includes sending, from a terminal device, a subscription topic name to a gateway to establish a data transmission channel between the terminal device and the gateway; receiving by the terminal device, via the data transmission channel, a certificate installation instruction from a certificate server; generating, by the terminal device, a user certificate request based on the certificate installation instruction; sending the user certificate request to the certificate server; and receiving, via the data transmission channel, a user certificate from the certificate server.
