Certificate Update Automation via Batch Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing certificate management systems fail to ensure that certificates are updated in a timely and efficient manner, leading to potential security breaches due to the use of obsolete encryption methods, which can prevent intended recipients from decrypting data.
Innovation Solution
A method and device for automatically updating certificates by determining the need for updates, requesting updates within a preset number, and setting timers to manage the update process, ensuring that only the most current certificates are used for encryption and decryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If certificates are updated frequently to maintain security, then security reliability is improved, but system complexity and processing overhead increase
Solution Approach 1:
The system automatically determines which certificates need updating and requests updates autonomously without manual intervention. The device monitors certificate validity periods and initiates update requests when necessary, making the system self-managing and reducing operational complexity.
Solution Approach 2:
The system proactively checks certificate validity periods and requests updates before certificates expire. By performing preliminary actions to identify and update certificates in advance, the system prevents security breaches while maintaining organized control over the update process.
2Reliability
If all certificates are updated simultaneously, then security is improved, but processing time and energy consumption increase
Solution Approach 1:
The system segments the certificate update process by determining the number of certificates requiring updates and comparing it against a preset threshold. When the number exceeds the threshold, updates are processed in batches rather than all at once, dividing the workload into manageable segments that reduce processing time and energy consumption.
Solution Approach 2:
The system updates only the necessary portion of certificates in each processing cycle rather than all certificates simultaneously. By updating a controlled number of certificates per cycle (preset number), the system achieves sufficient security improvement while avoiding the excessive processing burden of updating all certificates at once.
3Productivity
If certificate updates are delayed, then processing overhead is reduced, but security reliability deteriorates due to obsolete encryption methods
Solution Approach 1:
The system continuously monitors and determines the validity periods of certificates, using this feedback information to trigger update requests when certificates approach expiration. This feedback mechanism ensures certificates are updated timely to maintain security while avoiding unnecessary updates that would waste processing resources.
4Device complexity
If manual certificate update management is used, then system complexity is reduced, but time loss increases due to manual intervention requirements
Solution Approach 1:
The system automatically determines which certificates need updating, requests updates from certification authorities, and manages the update process without manual intervention. This self-service capability eliminates the time loss associated with manual certificate management while maintaining reasonable system complexity through automated workflows.
Data Source
AI summary
A method updates certificates for potential recipients. The method comprises determining whether the certificates require updating. The method comprises determining a number of the certificates that require updating. The method comprises requesting updates for each of the certificates that require updating when the number is at most a preset number and sets a timer to a first time duration. The method comprises requesting updates for up to the preset number of the certificates that require updating when the number is greater than the preset number and sets the timer to a second time duration.
