Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bundle transfer is performed between smart secure media, then productivity is improved through efficient transmission, but reliability deteriorates due to lack of secure state configuration and verification mechanisms
Solution Approach 1:
The patent implements feedback mechanisms through attestation verification. The transmitting terminal receives attestation information from the receiving terminal regarding bundle installation status, and the receiving terminal receives attestation information from the transmitting terminal regarding bundle deletion status. This closed-loop feedback ensures reliable state configuration while maintaining efficient transfer operations.
Solution Approach 2:
The patent uses attestation information as an intermediary to mediate the bundle transfer process. Rather than directly transferring bundle state, the system exchanges cryptographic attestation proofs that verify the state changes. This intermediary mechanism enables secure and reliable state configuration without compromising transfer efficiency.
2Reliability
If attestation verification is implemented for bundle transfer, then reliability is improved through secure verification, but device complexity increases due to additional verification steps
Solution Approach 1:
The patent uses attestation information as a cryptographic copy or proof of state rather than directly managing complex verification logic. The attestation serves as a simplified representation of the bundle state that can be verified without replicating the entire verification complexity in each terminal.
3Reliability
If bundle state configuration is performed after transfer, then reliability is improved through proper state management, but loss of time occurs due to additional configuration steps
Solution Approach 1:
The patent performs preliminary actions by having the receiving terminal generate attestation information about bundle installation status before the transmitting terminal deletes the original bundle. Similarly, the transmitting terminal generates attestation information about deletion status before the receiving terminal finalizes the installation. This preliminary action ensures reliable state management while minimizing time loss by avoiding rework.
