Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems fail to efficiently validate and transition new digital certificates in a computing network without causing downtime or security risks, particularly in cloud environments where network entities rely on certificate authorities for authentication.

Innovation Solution

A system orchestrates testing processes for new CA certificates by issuing and authenticating entity certificates in parallel with the current CA certificate, ensuring seamless transition and validation before superseding the current certificate, thereby maintaining network security and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a new CA certificate is issued to supersede the current CA certificate, then security is improved, but network entities experience downtime and service disruption during the transition

Engineering Contradiction:

ImprovesecurityVSAvoiddowntime

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary testing of the new CA certificate in a dedicated test environment before deploying it to production. Network entities are first issued and tested with entity certificates based on the new CA certificate to ensure compatibility and functionality. Only after successful testing does the system proceed to distribute the new CA certificate bundle to network entities, thereby preventing service disruption during the transition.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The certificate distribution process is segmented into distinct phases: testing phase (where the new CA certificate is validated in isolation) and deployment phase (where the new CA certificate is distributed to network entities). This segmentation allows the new certificate to be thoroughly tested without affecting ongoing network operations, and enables controlled rollout that minimizes downtime.

Inventive Principle:

Principle #1Segmentation

2Reliability

If a new CA certificate is distributed to network entities, then security is enhanced, but network entities may reject the new certificate due to validation failures

Engineering Contradiction:

ImprovesecurityVSAvoidcertificate validation compatibility

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The system implements a feedback mechanism where network entities that receive the new CA certificate bundle are monitored for validation errors or rejection. If validation failures are detected, the system can identify the scope of the problem and take corrective actions, such as rolling back the certificate distribution or adjusting the certificate configuration, thereby ensuring compatibility before full deployment.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Before distributing the new CA certificate to network entities, the system performs preliminary validation by issuing entity certificates based on the new CA certificate and testing them in a controlled environment. This preliminary action ensures that the new CA certificate is compatible with existing network entities and security protocols, reducing the likelihood of validation failures during actual deployment.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the current CA certificate is removed from the execution environment, then the new certificate takes effect, but network entities experience authentication failures during the transition

Engineering Contradiction:

Improvecertificate transition flexibilityVSAvoidauthentication

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary testing of authentication mechanisms with the new CA certificate before removing the current CA certificate from the execution environment. This ensures that network entities can successfully authenticate using the new certificate, and allows for any necessary adjustments to be made beforehand, thereby preventing authentication failures during the transition.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains the current CA certificate in the execution environment alongside the new CA certificate for a period, providing a cushion during the transition. This allows network entities to continue using the current certificate for authentication while gradually migrating to the new certificate, thereby preventing authentication failures and ensuring smooth transition.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A system orchestrates a testing process for testing a new certificate authority (CA) certificate in an execution environment prior to the new CA certificate superseding a current CA certificate in the execution environment. Orchestrating the testing process includes issuing a first entity certificate based on the new CA certificate for a first network entity executing in the execution environment that is designated for performing testing operations and distributing the first entity certificate to the first network entity for performing the testing operations. While performing the testing operations, the system distributes a second entity certificate, issued based on the current CA certificate, to a second network entity executing in the execution environment that is not designated for performing testing operations. The system removes the current CA certificate from the execution environment responsive to determining that the testing operations are successful, and the new CA certificate supersedes the current CA certificate.
