Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple security protocols are used across devices, then security coverage and versatility are improved, but system complexity and difficulty of centralized management increase
Solution Approach 1:
The patent introduces a configuration capability within the PCI Express protocol that acts as an intermediary layer between devices with different security protocols and the central processor. This capability includes a data structure that standardizes security parameter reporting, allowing the processor to manage multiple security protocols through a unified interface without direct complexity from each protocol implementation
Solution Approach 2:
The PCI Express configuration capability is designed as a universal mechanism that can handle multiple security protocols through a single standardized interface. The capability data structure is multi-functional, capable of reporting security characteristics across different security platforms while maintaining a consistent communication framework
2Adaptability or versatility
If devices operate independently under different security protocols, then device autonomy and security specialization are improved, but centralized provisioning and initialization capability deteriorate
Solution Approach 1:
The configuration capability implements a feedback mechanism where devices report their security characteristics and parameters back to the processor through the standardized PCI Express data structure. This feedback loop enables the processor to understand the security state of each device and perform centralized provisioning and initialization appropriate to each device's specific security protocol requirements
Solution Approach 2:
The standardized configuration capability serves as an intermediary that translates between device-specific security protocol parameters and the universal PCI Express communication framework, enabling centralized management while preserving device autonomy and protocol diversity
3Device complexity
If security parameters are not reported by devices, then device simplicity is maintained, but processor control over security features is reduced
Solution Approach 1:
The device automatically reports its security parameters and characteristics to the processor through the configuration capability without requiring manual configuration or additional complexity in the device. The reporting mechanism is self-activating and integrated into the device's operation, providing the processor with the information needed for security control while maintaining device simplicity
