Domain Zone Control Validation via Unique Pass String

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current domain zone validation methods lack secure and efficient mechanisms to verify control over domain zones, particularly in ensuring authenticity and preventing unauthorized access or impersonation.

Innovation Solution

A method involving the generation and verification of a unique Pass String, which is entered into specific fields of the domain zone file, such as TXT or CNAME records, to validate control over the domain zone, and optionally used to issue secure certificates by determining the Pass String's presence within the domain zone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional domain zone validation methods are used, then the validation process is simple, but security and authenticity are insufficient

Engineering Contradiction:

Improvesecurity and authenticity of domain zone control validationVSAvoidcomplexity of validation mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary validation actions by generating and placing a unique Pass String into the domain zone file before any certificate issuance or authorized operations. This preliminary placement of the validation string ensures that control authenticity is established beforehand, preventing unauthorized access while maintaining a relatively simple validation process.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a unique Pass String validation mechanism is implemented, then impersonation risks are reduced, but the validation process becomes more complex

Engineering Contradiction:

Improveimpersonation resistanceVSAvoidease of domain zone validation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The domain zone validation system performs self-service by automatically generating, placing, and verifying the unique Pass String without requiring complex manual intervention. The system autonomously manages the validation process, reducing impersonation risks while keeping the operation simple for users who only need to provide basic domain information.

Inventive Principle:

Principle #25Self-service

3Reliability

If strict validation control is enforced, then unauthorized access is prevented, but the process time increases

Engineering Contradiction:

Improveauthorization controlVSAvoidvalidation process time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs the authorization control action in advance by placing the unique Pass String into the domain zone file before any certificate issuance or authorized operations. This preliminary placement establishes control authenticity beforehand, enabling fast validation while preventing unauthorized access, thus reducing the time required for subsequent validation operations.

Inventive Principle:

Principle #10Preliminary action

AI summary

A requester requests a domain zone control validation from a validating entity. The validating entity generates a pass string. The requester enters the pass string into a domain zone. The validating entity determines if the pass string was entered in the domain zone. If the pass string is present in the domain zone, the domain zone control was successfully validated.
