Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical sniffing protection is implemented through encryption, then security against malicious actors is improved, but device complexity increases due to the encryption pipeline requirements
Solution Approach 1:
The encryption algorithm is divided into multiple pipeline stages, with each stage performing a specific round of encryption operations. This segmentation allows the encryption function to be distributed across multiple processing units, making the complex security protection task manageable and implementable through modular design.
Solution Approach 2:
The encryption pipeline incorporates user-configurable parameters including block size and number of rounds, allowing the system to dynamically adjust the encryption strength and performance characteristics based on security requirements and available resources.
2Productivity
If a pipelined encryption algorithm with multiple stages is used, then encryption performance is improved, but device complexity increases due to multiple stages and key schedulers
Solution Approach 1:
The encryption process is segmented into multiple pipeline stages, where each stage handles a specific round of encryption. This enables parallel processing of different data blocks through the pipeline, improving throughput while maintaining the complexity manageable through modular organization.
Solution Approach 2:
The pipelined design ensures continuous encryption processing by maintaining multiple stages of operation simultaneously, with each stage working on different portions of data. This continuous action improves encryption performance by eliminating idle time between processing steps.
3Adaptability or versatility
If user-configurable block size and rounds are implemented, then adaptability to different security needs is improved, but device complexity increases due to configuration options
Solution Approach 1:
The encryption system incorporates user-configurable parameters for block size and number of rounds, allowing the encryption algorithm to dynamically adapt to different security requirements and performance constraints through software configuration rather than hardware redesign.
Solution Approach 2:
The encryption pipeline is designed to handle multiple configuration options within a single unified architecture, making the system universally applicable to various security needs without requiring separate hardware implementations for different encryption parameters.
