Staggered Electronic Certificate Acquisition Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing techniques for updating electronic certificates face network congestion and server failures due to simultaneous requests from multiple information processing apparatuses, leading to delays and interruptions in certificate authority services.
Innovation Solution
An information processing apparatus is configured to automatically adjust the timing of electronic certificate acquisition requests, distributing these requests across a range of times to prevent simultaneous transmissions, using a protocol like SCEP, and adjusting the request timing based on the number of connected devices to manage network traffic effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple information processing apparatuses transmit electronic certificate issuance requests at the same time, then automatic certificate acquisition is achieved, but network congestion occurs and server response is delayed
Solution Approach 1:
The patent implements periodic action by setting different timing intervals for certificate issuance requests based on the number of apparatuses in the network. Each apparatus transmits requests at staggered intervals rather than simultaneously, converting a single concentrated action into multiple periodic actions distributed over time. This resolves the contradiction by maintaining automatic acquisition while preventing network congestion.
Solution Approach 2:
The patent applies dynamics by making the request timing flexible and adaptive rather than fixed. The transmission timing is dynamically adjusted based on the number of information processing apparatuses detected in the network, allowing the system to adapt its behavior to current network conditions. This resolves the contradiction by enabling automatic acquisition while adjusting timing to maintain network stability.
2Productivity
If a large number of electronic certificate issuance requests are transmitted simultaneously, then certificate updates are performed across all apparatuses, but server interruption occurs
Solution Approach 1:
The patent applies segmentation by dividing the simultaneous certificate update action into multiple segmented requests transmitted at different times. Instead of all apparatuses updating certificates at once, the system segments the update process by controlling each apparatus to transmit its request at a different timing interval, preventing server overload while maintaining overall update efficiency.
Solution Approach 2:
The patent uses periodic action to space out certificate issuance requests over time intervals. By implementing periodic transmission timing based on the number of apparatuses, the system maintains productive certificate updates while preventing server interruption through distributed timing, resolving the contradiction between update efficiency and server availability.
3Ease of operation
If certificate acquisition timing is set uniformly for all apparatuses, then centralized control is achieved, but network congestion and processing delays occur
Solution Approach 1:
The patent applies dynamics by transitioning from static uniform timing to dynamic adaptive timing. The system maintains centralized control through the controller but dynamically adjusts each apparatus's request timing based on the number of apparatuses in the network. This resolves the contradiction by preserving ease of centralized operation while eliminating processing delays through adaptive timing adjustment.
Solution Approach 2:
The patent implements parameter changes by modifying the timing parameter of certificate requests based on network conditions. The controller changes the timing parameter dynamically according to the number of information processing apparatuses, allowing centralized control to be maintained while optimizing acquisition timing to prevent delays and congestion.

AI summary
An electronic certificate acquisition timing set in an information processing apparatus is changed based on predetermined change information, and the acquisition of the electronic certificate is executed at the changed timing.
