Cross-Domain Guard Authentication via Ancillary Processor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High assurance cross-domain systems face challenges in eliminating non-authentic and unauthorized data sources while minimizing encryption overhead and audit complexity, as existing methods rely heavily on authentication and authorization processing.
Innovation Solution
A high assurance guard system that uses authentication and authorization methods to verify the authenticity and authorization of data sources, employing an isolated ancillary processor and audit network to determine if data packets are well-formed, authentic, and from authorized sources before allowing communication between secure networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy encryption and distributed local audit systems are implemented in cross-domain systems, then security is improved, but system complexity and processing overhead increase significantly
Solution Approach 1:
The patent segments the authentication and authorization functions into a separate dedicated processor (ancillary processor) that operates independently from the main cross-domain system. This separation isolates the complex security processing from the core system, reducing overall system complexity while maintaining high security standards through specialized hardware dedicated to authentication tasks.
Solution Approach 2:
The patent introduces an intermediary audit network that connects the ancillary processor to the cross-domain system. This intermediary layer handles the complex audit and authentication communication, allowing the main system to offload security processing responsibilities while maintaining security through the intermediary's specialized functionality.
2Reliability
If authentication and authorization processing is performed directly in the core cross-domain system, then security verification is ensured, but processing speed and system performance deteriorate
Solution Approach 1:
By segmenting authentication and authorization processing into a separate ancillary processor, the patent enables parallel operation where the main cross-domain system continues its primary data transmission functions while the ancillary processor handles security verification independently. This segmentation prevents authentication processing from becoming a bottleneck that would slow down overall system performance.
Solution Approach 2:
The ancillary processor operates autonomously to perform authentication and authorization verification without requiring the core cross-domain system to interrupt its main processing tasks. The ancillary processor self-manages the authentication workflow, including receiving authentication requests, verifying credentials, and returning authorization decisions, thereby maintaining high processing speed in the core system.
3Productivity
If traditional trust-based cross-domain systems are used without rigorous authentication, then processing efficiency is maintained, but security against non-authentic sources is compromised
Solution Approach 1:
The patent implements preliminary authentication verification through the ancillary processor before data packets are allowed to pass between secure networks. By performing authentication checks in advance through the dedicated processor, the system ensures source authenticity is verified without interrupting the main data flow, thus maintaining processing efficiency while eliminating non-authentic sources.
Solution Approach 2:
The audit network acts as an intermediary layer that enables rigorous authentication verification without requiring the core cross-domain system to handle the complex verification processes directly. This intermediary infrastructure provides the necessary security checks while allowing the main system to maintain its efficient data transmission operations.
Data Source
AI summary
Cross-Domain guard with authentication and authorization function used to protect data transferred between two separate and secure networks. The guard utilizes an existing audit port to provide the capability augment or replace data-forwarding decisions, which were previously being based solely on whether the data is in a well-formed packet. The authentication and authorization may be resident in a partition, a side car processor or a separate network.
