Cloud Browser Root Certificate Verification for Intranet Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not verify the reliability of intranet sites using cloud browsers operating on virtual machines outside the intranet, which lack dedicated root certificates for secure HTTPS connections.
Innovation Solution
An information processing apparatus on a virtual machine external to the intranet receives a root certificate from a communication terminal and verifies the reliability of intranet websites using this certificate during web page rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cloud browser on virtual machine outside intranet is used, then accessibility and calculation load reduction are improved, but reliability verification of intranet sites cannot be performed
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the virtual machine (cloud browser) and the intranet. The gateway receives root certificates from the communication terminal and provides them to the virtual machine, enabling the virtual machine to verify the reliability of intranet sites without being directly connected to the intranet. This mediator resolves the contradiction by allowing external access while maintaining security verification capability.
2Reliability
If dedicated root certificates are registered in communication terminal, then reliability verification of intranet sites is improved, but complexity of certificate management increases
Solution Approach 1:
The patent extracts the root certificate storage function from the communication terminal and relocates it to the gateway device. The communication terminal no longer needs to store and manage multiple root certificates locally. Instead, it simply transmits the necessary certificates to the gateway, which then provides them to the virtual machine. This extraction reduces the complexity of certificate management in the terminal while maintaining reliability verification capability.

AI summary
An information processing apparatus that provides a rendering result of a web page based on a request from a communication terminal connected to an intranet includes receiving a root certificate for a website on the intranet from the communication terminal and a performing, when the web page of the website on the intranet is rendered, verification of reliability of the website on the intranet with the root certificate.
