Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional digital processing systems are used to process digital bearer instruments, then system complexity is reduced, but security and reliability are compromised due to potential tampering and unauthorized changes
Solution Approach 1:
The patent applies preliminary action by pre-defining operating contexts and pre- verifying component integrity through digital signatures before the actual rights redemption process. The system预先 establishes trusted operating environments with integrity-verified components, so that when a digital bearer instrument is presented, the verification has already been performed, preventing tampering before it can affect the redemption process.
Solution Approach 2:
The patent introduces an intermediary layer of operating contexts and integrity verification mechanisms between the digital bearer instrument and the rights redemption process. This intermediary layer acts as a mediator that verifies the integrity of operating environment components through digital signatures and manifests, preventing direct interaction that could allow tampering while maintaining system functionality.
2Reliability
If integrity-verified components are instantiated for every operating environment, then tampering prevention is improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs integrity verification in advance by pre-defining operating contexts with digitally signed manifests that specify the required components and their integrity requirements. When an operating environment needs to be instantiated, the verification has already been performed on the manifest, significantly reducing the time required at the point of rights redemption while maintaining strong integrity guarantees.
Solution Approach 2:
The patent changes the parameter of verification from component-level real-time checking to manifest-level pre-verification. By shifting the verification parameter from individual component integrity at runtime to overall manifest integrity beforehand, the system achieves both high reliability and efficient processing, as the digitally signed manifest provides cryptographic assurance without requiring extensive runtime verification.
3Productivity
If selective instantiation of operating environment components is performed, then resource efficiency is improved, but the risk of incomplete or incorrect environment configuration increases
Solution Approach 1:
The patent introduces a manifest as an intermediary that mediates between the selective instantiation requirements and configuration correctness. The manifest serves as a trusted specification that defines exactly which components should be instantiated and with what parameters. This intermediary ensures that selective instantiation follows a pre-verified correct configuration, eliminating the risk of incomplete or incorrect environment setup while maintaining resource efficiency through selective component loading.
Solution Approach 2:
The patent performs preliminary configuration specification by embedding the complete operating context definition in the digitally signed manifest. This preliminary action captures all configuration requirements beforehand, so that selective instantiation can proceed confidently according to the pre-defined correct configuration, ensuring both resource efficiency and configuration correctness without trade-offs.
