Distributed Digital Certificate Validation via Local Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital certificate validation methods require clients to frequently connect and communicate with a central host for real-time validation results, which can be inefficient due to limited client resources and independent operation.
Innovation Solution
A distributed digital certificate validation method where clients establish an initial connection with the host, request and import certificate validation results, and store them locally for later retrieval, allowing for pre-validation and reducing the need for continuous communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clients connect and communicate with the host each time certificate validation is needed, then real-time validation results are obtained, but resource efficiency deteriorates due to frequent connections and limited client resources
Solution Approach 1:
The host performs certificate validation in advance and stores the validation results locally on clients. When validation is needed, clients simply retrieve pre-computed results from their local storage rather than connecting to the host, eliminating frequent communication overhead while maintaining validation accuracy.
Solution Approach 2:
Validation results are copied from the host to client local storage. Clients obtain copies of validation results that can be retrieved locally without requiring continuous connection to the host, reducing communication frequency while preserving result accuracy.
2Adaptability or versatility
If clients operate independently with limited resources, then system scalability is improved, but validation performance deteriorates due to resource constraints
Solution Approach 1:
The computationally intensive certificate validation process is extracted from resource-constrained clients and performed centrally on the host. Only the lightweight result retrieval operation remains on clients, allowing them to operate independently with minimal resources while achieving fast validation performance.
Solution Approach 2:
Local storage on clients acts as an intermediary between the host and validation operations. Validation results are stored locally and retrieved without requiring client resources to perform complex validation computations, enabling independent operation with limited resources while maintaining high performance.
3Loss of information
If clients make frequent connections to the host, then up-to-date validation results are obtained, but communication overhead increases
Solution Approach 1:
The host performs validation and prepares results in advance, storing them on clients before they are needed. This preliminary action eliminates the need for frequent communication to obtain up-to-date results, as clients already have current validation data locally available.
Solution Approach 2:
Instead of continuous or frequent connections, the system uses periodic batch updates where the host pushes validation results to clients at scheduled intervals. Clients retrieve results during these periodic updates rather than connecting continuously, reducing communication overhead while maintaining result freshness.
Data Source
AI summary
A distributed digital certificate validation method of a client connectable in communication with a host is provided. A first connection is made with the host to establish data communication with the host. A request for a certificate validation result is sent to the host. A file containing at least the requested certificate validation result is imported from the host and the imported file is stored locally for later retrieval of at least the requested certificate validation result.
