Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional software supply chains are used for aerospace systems, then software updates can be distributed, but the systems become vulnerable to malicious interference and tampering
Solution Approach 1:
A blockchain intermediary layer is introduced between the software supply chain and aerospace systems. The blockchain validates software packages through hash ID verification before installation, acting as a mediator that prevents malicious interference while allowing legitimate updates to proceed through the complex supply chain network.
Solution Approach 2:
The system performs preliminary validation of software packages against the blockchain record before installation on aerospace systems. The hash ID is verified in advance to ensure software integrity, and only after successful validation is the software installed, preventing tampered software from compromising system reliability.
2Reliability
If blockchain validation is implemented for software packages, then security and integrity are enhanced, but system complexity increases
Solution Approach 1:
Instead of storing the entire software package on the blockchain, the system creates and stores only a cryptographic hash ID (digital fingerprint) of the software package on the blockchain. This copying approach significantly reduces the data storage requirements and system complexity while maintaining the ability to verify software integrity through hash comparison.
Solution Approach 2:
The complex blockchain validation logic is extracted and centralized in a validation module that interfaces with the blockchain. This separation allows the validation functionality to be implemented as a distinct, manageable component that can be integrated into the dataloading system without overwhelming complexity throughout the entire aerospace system.
3Reliability
If comprehensive software validation is performed, then malicious software installation is prevented, but the time required for updates increases
Solution Approach 1:
The manual or mechanical process of software verification is replaced with automated cryptographic hash validation against the blockchain. The system automatically compares the software package hash with the blockchain record, eliminating time-consuming manual verification while ensuring comprehensive software verification reliability.
