Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verification certificates are managed during initial program load, then software authenticity and integrity are ensured, but processing complexity and time requirements increase
Solution Approach 1:
The patent applies preliminary action by performing verification certificate management operations during the initial program load phase, before the main software execution begins. The diagnose instruction is executed in advance to query and store verification certificates in the certificate store, ensuring that authentication mechanisms are pre-established and ready for subsequent software verification operations.
Solution Approach 2:
The patent introduces an intermediary mechanism through the diagnose instruction and certificate store, which act as mediators between the firmware and the software verification process. The diagnose instruction serves as an interface that simplifies certificate queries and storage operations, reducing the complexity burden on the main verification process while maintaining security requirements.
2Reliability
If verification keys are changed over time to protect them, then security is improved, but processing efficiency and compatibility across configurations deteriorate
Solution Approach 1:
The patent applies dynamics by enabling the verification system to adapt to changing verification keys over time. The diagnose instruction with subcodes allows the system to dynamically query and update verification certificates in response to key changes, while the certificate store maintains a current token that reflects the latest key configuration, ensuring both security updates and processing efficiency.
Solution Approach 2:
The patent implements feedback mechanisms where the current token in the certificate store provides feedback about the verification key status. When keys are changed, the system updates the token and makes this information available through the diagnose instruction, allowing subsequent operations to efficiently adapt to the new key configuration without redundant processing.
3Adaptability or versatility
If multiple verification certificates are stored and managed, then adaptability to different configurations is improved, but storage requirements and processing time increase
Solution Approach 1:
The patent applies segmentation by organizing verification certificates into a structured certificate store with indexed entries. Each certificate is stored as a discrete unit with associated metadata, allowing the system to manage multiple certificates efficiently. The diagnose instruction can query specific certificates or ranges of certificates, reducing the need to process all certificates simultaneously while maintaining adaptability to different configurations.
Data Source
AI summary
An instruction to be executed within the computing environment is obtained. The instruction includes an operation code indicating a diagnose operation. The instruction is executed. The executing includes obtaining a token as an input to the instruction and comparing the token to a current token for a configuration of the computing environment. Based on the token matching the current token, one or more verification certificates are returned from a certificate store.
