Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the digital certificate is split into multiple small packets for transmission, then the transmission can be completed, but the transmission duration increases and connection establishment failure rate increases
Solution Approach 1:
The patent applies segmentation by dividing the digital certificate transmission into two distinct phases: first transmitting the complete digital certificate for reliability, then transmitting a compressed version for efficiency. This resolves the contradiction by allowing the system to benefit from both complete transmission (high success rate) and compressed transmission (shorter duration) without compromising either aspect.
2Loss of time
If the digital certificate is transmitted in full without splitting, then the transmission duration is reduced, but the data transmission volume increases and may cause transmission failures
Solution Approach 1:
The patent applies parameter changes by transforming the digital certificate into a compressed format with different size parameters while maintaining its functional integrity. The compression changes the data volume parameter, allowing faster transmission while the verification mechanism ensures the transformed certificate remains reliable for identity verification purposes.
3Productivity
If compression is applied to the digital certificate, then the data transmission volume is reduced and transmission efficiency is improved, but verification complexity increases
Solution Approach 1:
The patent introduces an intermediary verification mechanism that mediates between the compressed certificate and the verification process. The intermediary layer performs consistency verification by comparing the compressed certificate against the original, adding a verification step that manages the complexity while enabling the use of compressed formats for improved communication efficiency.
Data Source
AI summary
This application provides a network communication method performed by a computer device acting as a second communication terminal. After transmitting an encrypted communication connection request for a first digital certificate to a first communication terminal, the second terminal receives a second digital certificate from the first communication terminal. The second terminal then receives a compressed digital certificate returned by the first communication terminal, the compressed digital certificate being obtained by the first communication terminal through compression of the first digital certificate. Next the second terminal performs consistency verification on the second digital certificate and the compressed digital certificate. After determining that the consistency verification succeeds the second terminal then generates an encrypted communication key; and performs encrypted communication with the first communication terminal based on the encrypted communication key.
