CRL Distribution Point Mapping for Current Certificate Revocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network entities in virtual cloud networks face challenges in maintaining and updating certificate revocation lists (CRLs), leading to potential authentication issues due to reliance on outdated CRLs, which can compromise security protocols.
Innovation Solution
A system is implemented to identify and serve current CRLs to network entities in response to requests, relieving them from the need to maintain and update CRLs, thereby ensuring compliance with security protocols by providing up-to-date authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network entities maintain and update CRLs themselves, then they can ensure up-to-date authentication information, but the operational complexity and resource requirements increase significantly
Solution Approach 1:
The patent introduces a CRL distribution point as an intermediary service that network entities query to obtain current CRLs. This mediator handles the complexity of CRL maintenance, updates, and distribution centrally, while individual network entities simply query the service without needing to maintain CRLs themselves, thus resolving the contradiction between authentication reliability and operational simplicity
Solution Approach 2:
The system enables network entities to autonomously retrieve current CRLs by querying the CRL distribution point service as needed. This self-service approach allows entities to obtain up-to-date authentication information without manual intervention or complex maintenance procedures, balancing reliability with ease of operation
2Reliability
If network entities periodically check for CRL updates, then they can maintain current authentication data, but this consumes additional time and computational resources
Solution Approach 1:
The CRL distribution point service pre-maintains and stores current CRLs ready for retrieval. When network entities query the service, they receive immediately available up-to-date CRL information without needing to perform periodic checks or wait for updates, thus ensuring CRL currency while minimizing resource consumption during authentication operations
3Productivity
If network entities use outdated CRLs, then authentication processes become faster and simpler, but security compliance is compromised
Solution Approach 1:
The CRL distribution point acts as a trusted intermediary that provides network entities with current CRLs upon request. This allows authentication processes to proceed quickly by querying the service rather than maintaining local CRL copies, while simultaneously ensuring security compliance by guaranteeing that entities receive authoritative, up-to-date revocation information from the trusted source

AI summary
Operations may include receiving, from a first network entity, a first request for a first certificate revocation list (CRL) that identifies a first CRL distribution point (CDP) corresponding to the first CRL; mapping the first CDP to a first CRL identifier of a set of available CRL identifiers; locating, in a CRL repository, a first CRL based on the first CRL identifier; and transmitting the first CRL to the first network entity.
