Solution Overview

Problem

Current aircraft maintenance processes require physical presence and direct connection to the Aircraft Data Gateway (ADG) for software and data operations, leading to inefficiencies, increased administrative burdens, and potential security risks due to unauthorized access.

Innovation Solution

Implementing a multi-factor digital authentication system using an authentication server to securely transmit data and perform operations remotely, allowing authorized users to initiate and monitor software and data updates through a remote operations portal, with the ADG performing first and second digital authentications before executing operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical security measures are used to protect the ADG by locating it in the aircraft cockpit, then unauthorized access is prevented, but operational efficiency and ease of remote maintenance are reduced

Engineering Contradiction:
ImprovesecurityVSAvoidremote operation capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces an authentication server as an intermediary between the remote device and the ADG. This server mediates the authentication process by receiving authentication requests from remote devices, performing multi-factor authentication, and communicating with the ADG to verify credentials. This allows secure remote access without requiring the ADG to be physically present in the cockpit, thus resolving the contradiction between security and remote operation capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/physical security system (physically securing the ADG in the cockpit) with a digital authentication system. Instead of relying on physical location and access control, the system uses electronic authentication credentials, digital signatures, and cryptographic verification to secure access. This substitution enables remote operations while maintaining security, as the ADG can be accessed remotely through validated digital credentials without being physically present in the cockpit.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If physical presence is required for software and data operations, then security is maintained, but administrative burden and time consumption increase

Engineering Contradiction:
ImprovesecurityVSAvoidtime for maintenance operations
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-configuring multiple authentication credentials and factors in the authentication server before remote operations are needed. The system pre-establishes trusted relationships between the ADG, authentication server, and authorized remote devices through prior authentication and credential distribution. This preliminary setup enables rapid authentication during actual operations without requiring time-consuming manual verification processes, thus reducing the time loss while maintaining security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables self-service by allowing the ADG and remote devices to perform automated authentication exchanges without human intervention. The authentication server handles credential verification, token generation, and security validation automatically through programmed protocols. This automated self-service mechanism eliminates the need for administrative personnel to physically present and manually verify credentials, significantly reducing both time consumption and administrative burden while maintaining robust security through multi-factor authentication.

Inventive Principle:
Principle #25Self-service

3Device complexity

If direct connection to ADG is required for operations, then access control is simplified, but operational flexibility and remote capability are limited

Engineering Contradiction:
Improveaccess control mechanismVSAvoidremote operation flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent adds another dimension to the access control mechanism by introducing a network communication dimension. Instead of solely relying on physical connection dimensions (direct cable connections to ADG), the system establishes authentication and communication channels through network protocols over distance. This dimensional expansion allows the ADG to maintain secure access control while accepting connections from remote devices through authenticated network channels, thus increasing operational flexibility without significantly increasing access control complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Methods and systems for authenticating operations of an aircraft are disclosed. In at least one embodiment, the method may include: receiving, by an aircraft data gateway, a request for an operation of an aircraft from an operations portal; performing a first digital authentication of the request using first digital authentication information; performing a second digital authentication of the request using second digital authentication information, the second digital authentication information being distinct from the first digital authentication information; and executing the operation of the aircraft upon validating the first digital authentication and the second digital authentication.
