Federated Security Controller for Mobile Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional centralized computing system architectures for mobile structures lack data and execution security, and have limited upgrade paths due to proprietary interfaces and regulatory restrictions, which negatively impact marketability and maintenance costs.
Innovation Solution
A secure federated computing system architecture that includes a secure system controller and user modules with common secure system processors, forming secure communication channels over system fabrics to dynamically allocate secure and non-secure resources based on a security rule set, allowing for modular upgrades and high-security configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional centralized computing system architectures are used, then system integration is achieved, but data and execution security are compromised
Solution Approach 1:
The system is divided into multiple secure domains (secure domain 102, semi-secure domain 104, non-secure domain 106) with isolated execution environments. Each domain has its own security boundaries and access controls, preventing security compromises from propagating across the entire system while maintaining overall system functionality.
Solution Approach 2:
A security manager 116 is introduced as an intermediary component that mediates access between different security domains. The security manager enforces security policies, manages cryptographic keys, and controls resource allocation, providing a centralized security control mechanism without requiring complete system redesign.
2Reliability
If proprietary interfaces and protocols are enforced for security, then security compliance is achieved, but upgrade paths are severely limited
Solution Approach 1:
The system employs universal security interfaces and standardized protocols that work across multiple security domains and device types. The security manager can manage diverse subsystems (avionics, entertainment, communication) through common security mechanisms, allowing upgrades without requiring proprietary interface changes.
Solution Approach 2:
The security architecture is designed to be dynamic and configurable, with security policies and access controls that can be modified without hardware changes. The system can adapt security parameters and resource allocations based on operational requirements, enabling flexible upgrades while maintaining security compliance.
3Ease of manufacture
If unsecured technology is used to reduce costs, then manufacturing expenses are reduced, but regulatory restrictions apply
Solution Approach 1:
The system applies different security levels to different components and domains based on their specific requirements. Critical subsystems receive higher security protection while less critical components can use more cost-effective solutions, optimizing the balance between manufacturing cost and regulatory compliance across the entire system.

AI summary
Techniques are disclosed for systems and methods to provide a secure federated computing system for mobile structures. A secure federated computing system includes a secure system controller and one or more user modules each implemented with a secure system processor and configured to communicate over one or more system fabrics. The secure system controller and the user modules are configured to form secure communication channels to each other over the one or more system fabrics to facilitate a secure initialization procedure. Once the secure initialization procedure is complete, the secure system controller and the user modules can be used to dynamically allocate secure and non-secure system resources as needed or as indicated by a security rule set programmed into the secure system processor.
