Cross-Domain Hub for Secured and Non-Secured Data Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Field-users of secure mobile devices face challenges in integrating non-secured data sources with secured systems due to differing security classification levels, leading to blocked data flow and potential loss of critical information.
Innovation Solution
A hub device is configured to receive data packets from both secured and non-secured client devices, performing guard processes to ensure integrity and security, allowing non-secured data to be processed and forwarded to a host device while maintaining the security of secured data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-secured data sources are integrated with secured systems, then the effectiveness and mission completion ability of field-users is improved, but the security classification level differences block data flow between secured and non-secured devices
Solution Approach 1:
A cross-domain hub is introduced as an intermediary device between secured and non-secured data sources. The hub receives data from both secured devices (at higher classification levels) and non-secured devices (at lower classification levels), performs appropriate guard processes based on data origin, and forwards validated data to the destination. This mediator resolves the contradiction by enabling data flow across classification boundaries while maintaining security through protocol enforcement.
2Reliability
If guard processes are performed on data packets from non-secured devices, then the integrity and security of the system is maintained, but the complexity of data processing increases
Solution Approach 1:
The cross-domain hub applies different guard processes to data packets based on their origin and security classification. Data from secured devices undergoes one type of validation, while data from non-secured devices undergoes more stringent guard processes. This localized differentiation of processing intensity resolves the contradiction by maintaining high security for critical data while reducing unnecessary processing complexity for already-secured data.
3Reliability
If data flow is blocked between different security classification levels, then the security of secured devices is protected, but the ability to share critical information is lost
Solution Approach 1:
The cross-domain hub serves as a controlled intermediary that enables information sharing between secured and non-secured domains. Instead of complete blocking, the hub selectively permits data flow after applying appropriate guard processes, thus preventing information loss while maintaining security protection through controlled access rather than total isolation.

AI summary
In general, the techniques of this disclosure describe a hub device that is configured to receive data packets from both secured client devices and non-secured client devices. The hub device may send the data packets from the secured client devices to a host device. For the data packets from the non-secured client devices, the hub device may first process the data packets to ensure the integrity of the received non-secure data packets and then send the non-secure data packets to the host device once the hub device determines that the non-secure data packets meet some threshold level of integrity.
