Proxy and Transactional Digital Certificate Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital certificate systems face challenges in managing long-lasting validation certifications while ensuring short-term validity for specific transactions, as user information may change over time, leading to overload in validation processes.
Innovation Solution
A computerized system and method for managing digital certificates, utilizing a Certificate Authority Computer System (CACS) that issues Proxy Digital Certificates (PCERT) and Transactional Digital Certificates (TCERT), with multi-factor authentication and real-time validation, allowing for short-term TCERT issuance based on transaction data validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If digital certificates are issued with long validity periods (one to two years), then the validation process is reduced and user convenience is improved, but user information may change during this period leading to security risks and validation overload
Solution Approach 1:
The patent segments the digital certificate validity into two distinct types: Proxy Digital Certificates (PCERT) with long validity periods for identity establishment, and Transactional Digital Certificates (TCERT) with short validity periods for specific transactions. This segmentation allows long-term identity validation without compromising transaction-specific security requirements, resolving the contradiction between reduced validation frequency and maintained reliability.
Solution Approach 2:
The system dynamically adjusts certificate validity based on the specific use case. PCERT provides long-term validity for stable identity attributes, while TCERT provides short-term validity for transient transactions. The system can also dynamically validate user information during the certificate lifecycle, adapting the validation approach to the current state of user data rather than using a static validation schedule.
2Reliability
If digital certificates are issued with short validity periods to ensure current user information accuracy, then security is improved, but the validation process becomes overloaded and less efficient
Solution Approach 1:
By separating identity validation (PCERT) from transaction validation (TCERT), the system avoids redundant validation of stable identity attributes for each transaction. The PCERT validates long-term identity characteristics once, while TCERT handles short-term transaction-specific validation, significantly improving validation efficiency while maintaining information accuracy.
Solution Approach 2:
The system performs preliminary validation of user identity information when issuing the PCERT, establishing a baseline of trusted attributes. This preliminary action reduces the need for repeated full validations during subsequent transactions, as the PCERT already contains validated identity data that can be referenced without re-validation, thereby improving productivity while maintaining reliability.
3Reliability
If comprehensive user information is validated at certificate issuance to ensure security, then authentication strength is improved, but the complexity of the registration process increases
Solution Approach 1:
The registration and validation process is segmented into two phases: PCERT issuance with comprehensive identity validation for long-term attributes, and TCERT issuance with focused transaction-specific validation. This segmentation allows comprehensive authentication to be performed once during PCERT registration, reducing the perceived complexity for users while maintaining strong authentication standards.
Solution Approach 2:
The PCERT acts as an intermediary that encapsulates validated user identity information. Instead of requiring comprehensive validation for every transaction, the PCERT serves as a pre-validated intermediary credential that streamlines subsequent TCERT issuance and transaction processing, reducing registration complexity while maintaining authentication strength.
