Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If cypher configuration is made before device deployment with available information, then configuration can be established in advance, but the configuration may be inconsistent and inferior due to insufficient information about computation power and specific device requirements
Solution Approach 1:
The system performs preliminary configuration actions by establishing a default cypher configuration during device manufacturing or initialization. This preliminary configuration uses available information at that time, allowing the device to be deployed immediately. The configuration is then refined later when complete device parameters and computation power information become available, resolving the contradiction between early configuration establishment and configuration quality.
Solution Approach 2:
The cypher configuration is designed to be dynamic rather than static. The system allows configuration parameters to be updated and adjusted after initial deployment based on actual device performance data and computation power measurements. This dynamic approach enables the configuration to evolve from an initial approximate state to an optimized state, addressing both the need for early configuration and the requirement for high quality.
2Reliability
If strong cypher configuration is applied to enhance security, then security coverage is improved, but CPU utilization increases and causes bottleneck for real-time device communication
Solution Approach 1:
The system dynamically adjusts cypher configuration parameters such as key length, algorithm complexity, and encryption strength based on the actual computation power and performance characteristics of each device. By changing these parameters to match device capabilities, the system achieves adequate security coverage without applying uniformly strong encryption that would overwhelm weaker devices and bottleneck real-time communication.
Solution Approach 2:
Different cypher configuration strengths are applied to different devices based on their individual computation power and requirements. Rather than applying a uniform strong configuration to all devices, the system tailors the security level to each device's local capabilities, ensuring that each device receives appropriate security protection without unnecessary computational overhead that would harm real-time communication performance.
3Stability of the object's composition
If cypher configuration is locked after initial setup to maintain stability, then configuration consistency is preserved, but the configuration becomes outdated as new security threats develop
Solution Approach 1:
The cypher configuration system transitions from a static locked state to a dynamic state that allows controlled updates. The configuration can be modified in response to new security threats, vulnerability discoveries, or device performance data. This dynamic approach maintains stability through version control and gradual updates while enabling adaptation to evolving security requirements, resolving the contradiction between configuration stability and threat response adaptability.
Solution Approach 2:
The system implements feedback mechanisms that monitor security threats, vulnerability information, and device performance continuously. Based on this feedback, the cypher configuration can be automatically adjusted or updated to address new threats while maintaining overall stability. The feedback loop ensures that configurations remain current and effective without requiring complete reconfiguration, balancing stability with adaptability.
4Reliability
If manual configuration by trained developers is performed to ensure adequate security, then configuration expertise is utilized, but the process becomes costly and cumbersome especially for multiple devices with different requirements
Solution Approach 1:
The system enables automated self-service configuration where devices automatically receive appropriate cypher configurations based on their reported device parameters and computation power. The automated system evaluates device characteristics and selects optimal security configurations without requiring manual intervention by trained developers. This self-service approach maintains configuration adequacy through algorithmic decision-making while dramatically reducing the cost and complexity of managing multiple devices with different requirements.
Solution Approach 2:
The system creates a universal configuration management platform that handles diverse device types and security requirements through a single automated system. Rather than requiring separate manual configuration processes for each device, the universal system applies consistent principles and algorithms across all devices, adapting to individual characteristics while maintaining overall management simplicity and reducing dependency on specialized developer resources.
