Solution Overview
Problem
Existing data management systems in the chemical fiber industry face security challenges due to frequent decryption of data during transmission, which compromises the integrity and security of yarn spindle product data across multiple work stages.
Innovation Solution
A data management system where work nodes encrypt data locally and data aggregation servers decrypt and re-encrypt data, ensuring security by minimizing direct decryption at individual nodes, and using different encryption algorithms to enhance protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is decrypted at each work node during transmission, then data can be processed and transmitted across work stages, but data security and integrity are compromised
Solution Approach 1:
Data is encrypted at the source work node before transmission begins. The encryption operation is performed in advance on all data packets that will be transmitted across work stages, ensuring that data remains protected throughout the entire transmission process without requiring decryption at intermediate nodes.
Solution Approach 2:
An aggregation server acts as an intermediary that receives encrypted data from multiple work nodes, performs centralized decryption only when necessary for aggregation operations, and re-encrypts data before forwarding to the next work stage. This mediator approach minimizes the number of decryption events while maintaining data processing capability.
2Reliability
If data is encrypted at each work node, then data security is improved, but computational cost and system complexity increase
Solution Approach 1:
Multiple work nodes aggregate their encrypted data at a centralized aggregation server. Instead of each node independently managing encryption and decryption operations, the system merges these operations at the aggregation server, reducing overall system complexity while maintaining security through centralized control of decryption events.
Solution Approach 2:
Encryption is performed preliminarily at each work node using standardized algorithms, but the complex decryption operation is deferred to the aggregation server. This preliminary encryption approach simplifies the overall system architecture by establishing security at the source without requiring complex decryption capabilities at each individual node.
3Reliability
If data is transmitted in encrypted form across all work stages, then data leakage is reduced, but data transmission and processing efficiency decreases
Solution Approach 1:
The aggregation server serves as an intermediary that selectively decrypts data only when aggregation operations are required. This mediator approach maintains encrypted transmission across most work stages (preserving security and efficiency) while enabling necessary decryption at controlled points for data aggregation and processing.
Solution Approach 2:
Instead of decrypting all data at all stages (excessive action), the system applies decryption only partially - specifically at aggregation servers when data from multiple sources needs to be combined. This partial decryption approach maintains security for the majority of transmission while enabling necessary processing efficiency where required.
