Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If distributed graphics processors are used for video processing, then processing capability is enhanced, but communication security deteriorates
Solution Approach 1:
The patent introduces an encryption intermediary layer between distributed graphics processors. Encryption keys are generated and managed through a key management system that acts as an intermediary, securing communications without interfering with the distributed processing capability. The encryption layer mediates data transmission between GPUs, preventing unauthorized access while maintaining processing productivity.
2Object-affected harmful factors
If encryption is implemented between graphics processors, then communication security is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal key management system that serves multiple functions: key generation, key distribution, key storage, and key revocation. This multi-functional approach consolidates what could be multiple separate security mechanisms into a single system, reducing overall complexity while maintaining comprehensive security across all GPU communications.
Solution Approach 2:
The encryption system is designed to be self-managing through automated key generation and distribution mechanisms. The key management system automatically handles key lifecycle operations without requiring manual intervention, reducing operational complexity while maintaining security. The system self-configures encryption parameters and manages security credentials autonomously.
3Object-affected harmful factors
If communication encryption is added to distributed graphics processing, then security against unwanted access is improved, but processing speed may deteriorate
Solution Approach 1:
Encryption keys are generated and distributed in advance before actual video processing operations begin. The key management system pre-configures security credentials for all participating graphics processors, so that during actual processing, encryption operations are minimized to only the necessary data transmission steps, reducing speed impact while maintaining security.
