Solution Overview

Problem

Current satellite communications radio systems for aircraft are unable to utilize the Enhanced SwiftBroadband Safety service due to the lack of technology to form an encrypted connection with a service gateway, limiting secure communication capabilities.

Innovation Solution

A secure communications data processor, comprising an IP interface system separate from the satellite communications radio system, which includes a router, IP processing system, encryption system, and communication manager, enables the formation of an encrypted connection using IP-based packet switching, allowing secure communication between the aircraft and ground facilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing satellite communications transceivers are used, then device complexity is reduced, but secure communication capability is lost

Engineering Contradiction:
Improvesecure communication capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an IP interface system as an intermediary component between the existing satellite communications transceiver and the Enhanced SwiftBroadband Safety service. This IP interface system includes IP processing functionality that enables secure IP-based packet switching communications without requiring modifications to the existing transceiver hardware, thus maintaining simplicity while adding security capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If encryption technology is added to existing transceivers, then communication security is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication securityVSAvoidtransceiver complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the communication system into distinct functional components: the existing satellite communications transceiver handles radio frequency operations, while a separate IP interface system handles IP processing and encryption. This segmentation allows encryption technology to be added without complicating the transceiver itself, as the security functions are isolated in the IP interface system.

Inventive Principle:
Principle #1Segmentation

3Reliability

If IP-based packet switching with encryption is implemented, then communication security is enhanced, but ease of operation is reduced

Engineering Contradiction:
Improvecommunication securityVSAvoidsystem operation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The IP interface system is designed to automatically perform IP processing, encryption, and decryption operations without requiring manual intervention. The system self-manages the formation of encrypted connections with service gateways and handles packet switching operations autonomously, maintaining ease of operation despite the enhanced security functionality.

Inventive Principle:
Principle #25Self-service
