Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current encryption units are used in multilevel security systems, then security classification handling is maintained, but interoperability efficiency deteriorates
Solution Approach 1:
The system segments the cryptographic processing function into separate cryptographic assemblies (local and coalition) that can independently process different cryptographic signals. Each assembly handles specific cryptographic operations for its designated domain, allowing efficient interoperability between different security classifications without requiring a single monolithic encryption unit to handle all cases.
Solution Approach 2:
The common hardware module is designed with universal functionality to receive and process both local cryptographic signals and coalition cryptographic signals. This multi-functional design enables the system to handle multiple cryptographic systems and security classifications within a single integrated platform, improving interoperability efficiency while maintaining security classification integrity.
2Adaptability or versatility
If multiple cryptographic systems are supported, then interoperability is improved, but system complexity increases
Solution Approach 1:
The system divides the cryptographic processing into separate, dedicated assemblies (local cryptographic assembly and coalition cryptographic assembly), each responsible for specific cryptographic systems. This segmentation reduces the complexity burden on any single component while enabling support for multiple cryptographic systems through modular architecture.
Solution Approach 2:
The common hardware module acts as an intermediary between different cryptographic assemblies and external communication channels. It provides a standardized interface for receiving and processing various cryptographic signals, abstracting the complexity of multiple cryptographic systems from the overall architecture and enabling interoperability through a unified mediation layer.
3Reliability
If cross-domain guards are implemented, then security clearance control is improved, but processing overhead increases
Solution Approach 1:
Each cryptographic assembly includes its own cross-domain guard mechanism tailored to its specific security domain. The local cryptographic assembly enforces security clearances for local communications, while the coalition cryptographic assembly does the same for coalition communications. This localized approach to security control reduces unnecessary processing overhead by applying security checks only where needed rather than uniformly across the entire system.
