Position: Certifiable State Integrity Should Be Built from Local Validity, Not Global Scale
TL;DR
A new approach to ensuring Certifiable State Integrity in Cyber-Physical Systems (CPS) emphasizes local validity over global models. This method enhances safety and adaptability by organizing assurance evidence around finite, locally valid models.
✦ Why It Matters
Consider adopting local validity models in your CPS projects to improve safety and adaptability.
Key Takeaways
- Implement locally valid models for better system assurance.
- Utilize the HYDRA architecture for modular safety analysis.
- Focus on explicit coverage-gap monitoring in CPS.
- Separate whole-system certification from local model validation.
How It Works
The HYDRA architecture operates by maintaining frozen local specialists that are tailored to specific operating conditions. These specialists are combined through runtime arbitration, allowing the system to adapt to changing conditions while ensuring that each model's validity is explicitly monitored.
This modular structure supports formal analysis and auditability, enhancing the overall integrity of the system.
