Dual-Layer Encryption for Classified Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Government and military entities face challenges in securely accessing and managing classified IP networks in dynamic operational environments without exposing sensitive information, as connecting classified devices to public IP networks for access or configuration is against security policy.
Innovation Solution
A wide area network access management computer system using NSA-approved CSfC Comprised Solutions, which implements a dual-layer encryption approach with hardware or software components to enable secure communication between classified devices and public IP networks, allowing access to sensitive data without direct connection to the public internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If classified devices are connected to public IP networks for access or configuration, then network accessibility and management capability are improved, but security policy compliance and protection of sensitive information deteriorate
Solution Approach 1:
The patent introduces an intermediary system consisting of a classified network interface card and a public network interface card that acts as a mediator between classified devices and public IP networks. This intermediary enables network accessibility while maintaining security isolation, allowing configuration and management operations without direct connection of classified devices to public networks, thus resolving the contradiction between ease of operation and security compliance
2Reliability
If dual-layer encryption is implemented to enable secure communication, then security protection and policy compliance are improved, but device complexity and system configuration difficulty worsen
Solution Approach 1:
The patent merges multiple security functions into a unified dual-layer encryption system where the classified network interface card and public network interface card work together as an integrated security architecture. This combination provides comprehensive security protection through layered encryption while managing complexity through unified system design, resolving the contradiction between reliability and device complexity
3Object-affected harmful factors
If classified devices remain isolated from public networks to prevent inadvertent disclosure, then information security is improved, but network connectivity and operational flexibility deteriorate
Solution Approach 1:
The patent segments the network interface into distinct classified and public components, with the classified network interface card handling secure communications and the public network interface card handling public network access. This segmentation enables classified devices to maintain isolation for information security while still providing network connectivity through the segmented public interface, resolving the contradiction between information security and adaptability
Data Source
AI summary
A system, method, and apparatus for providing secure communications to one or more users through an unclassified network. The system may include a network access management device may have a plurality of internal data network communications interfaces configured to communicate with at least one classified computing device using a National Security Agency (NSA) Commercial Solution for Classified (CSfC) comprised solution and an external data network communications interface configured to communicate with an unclassified network. A network access management device may use an inner NSA CSfC approved tunneling technology, an outer NSA CSfC approved tunneling technology, and a processor configured to perform processing and routing protocols associated with interconnecting the internal data network communications interface and the external data network communications interface.
