Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single key service provider is used for encryption, then the encryption service is simple to implement, but the availability and compatibility across different runtime environments deteriorates
Solution Approach 1:
The encryption service is segmented into multiple independent key service providers, each capable of operating autonomously. This allows the system to divide the encryption functionality across multiple providers rather than relying on a single provider, thereby improving availability while maintaining implementation simplicity through modular design.
Solution Approach 2:
The encryption framework is designed to be universal by supporting multiple key service providers through a common interface. This multi-functionality allows the same encryption service to work across different runtime environments and cryptographic requirements, resolving the contradiction between simplicity and availability.
2Reliability
If multiple key service providers are supported, then the compatibility and availability across runtime environments improve, but the system complexity increases
Solution Approach 1:
An intermediary encryption framework is introduced that mediates between the application and multiple key service providers. This intermediary layer abstracts the complexity of managing multiple providers, presenting a unified interface to applications while handling the intricacies of provider selection and coordination internally.
Solution Approach 2:
The system uses parameter changes to adapt to different runtime environments by dynamically selecting appropriate key service providers based on environmental parameters. This allows the framework to maintain simplicity from the user perspective while accommodating multiple providers through configurable parameters.
3Adaptability or versatility
If environment-specific encryption modules are used, then the cryptographic requirements are met, but the ease of operation and portability deteriorates
Solution Approach 1:
The encryption framework achieves universality by designing a single operational interface that works across all environments. Applications interact with the same encryption API regardless of the underlying key service provider or runtime environment, maintaining ease of operation while adapting to different cryptographic requirements through the framework's internal provider selection logic.
