Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware-based root of trust features are used to secure authentication, then security reliability is improved, but device complexity increases due to dedicated hardware modules
Solution Approach 1:
The patent combines user persona information with device identity information to create a unified certificate that integrates both authentication factors. This merging approach allows the system to leverage hardware-based root of trust features for security while avoiding the need for separate hardware modules for each authentication factor, thus improving security reliability without proportionally increasing device complexity.
Solution Approach 2:
The generated certificate serves multiple functions: it authenticates the device identity, verifies user persona information, and enables secure interactions across different systems. This multi-functionality reduces the need for separate authentication mechanisms, thereby maintaining high security reliability without requiring additional dedicated hardware modules for each function.
2Adaptability or versatility
If digital certificates are generated combining user persona and device identity, then trust extension capability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a certificate management system that acts as an intermediary between the device, user persona information, and target systems. This intermediary handles the complex tasks of certificate generation, validation, and management, thereby enabling robust trust extension capability while shielding the end systems from the underlying complexity of certificate operations.
Solution Approach 2:
The system transforms multiple authentication parameters (device identity, user persona information, biometric data) into a single standardized certificate format. This parameter transformation simplifies the trust extension process by converting complex multi-factor authentication data into a universally acceptable certificate structure that can be easily validated across different systems.
3Reliability
If biometric data is captured and processed for persona verification, then authentication security is improved, but processing time increases
Solution Approach 1:
The system performs preliminary processing of biometric data during the certificate generation phase, extracting and encoding essential persona verification features in advance. This preliminary action prepares the biometric information for rapid comparison during subsequent authentication operations, thereby maintaining high authentication security while significantly reducing the time required for actual verification processes.

AI summary
A user device implements a certificate authority for issuing digital certificates that extend to other computing devices a level of trust to a particular user paired with the user device. The user device may obtain user persona information, generate a user key, and combine the user key with a device key for the generation of a digital certificate. The computing device may further transmit the digital certificate to a certificate management system, which manages interactions between other computing devices and the user device or authorizes operation of other computing devices by the particular user based on the digital certificate.
