Command Authentication Codes for Unsecured Remote Control Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remotely controlled transport systems, the failure of uplink connections leads to increased risk of accidents due to the inability to authenticate and verify command data, potentially allowing third-party interference and incorrect command execution, which overburdens air traffic control units without proper training.
Innovation Solution
An apparatus comprising a receiving unit, processor unit, and memory unit with a code generator, cryptography module, and comparison module that generates and verifies authentication codes using a private key, allowing secure command data transmission over unsecured data connections, ensuring only authorized commands are executed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If command data is transmitted via an unsecured data connection in the event of uplink failure, then the means of transport can still receive commands, but the system becomes vulnerable to third-party interference and falsified commands
Solution Approach 1:
The system performs preliminary actions by generating and transmitting a transaction code via the unsecured connection before the actual command transmission. This transaction code serves as a preliminary authentication mechanism that enables subsequent verification of command authenticity without requiring a secured connection
Solution Approach 2:
The patent introduces an intermediary authentication mechanism using transaction codes and authentication codes. These codes act as mediators between the unsecured data connection and the command execution system, enabling verification of command authenticity without requiring direct security measures on the communication channel
2Productivity
If air traffic control units assume the role of remote operator to forward commands, then command transmission is maintained, but the workload increases and accident risk rises due to lack of training
Solution Approach 1:
The system enables self-service operation by equipping the means of transport with autonomous authentication capabilities. The apparatus on the means of transport independently verifies command authenticity using the authentication code and private key, eliminating the need for air traffic control personnel to perform complex authentication tasks or assume remote operator roles
3Speed
If no authentication mechanism is used on unsecured connections, then transmission speed is maintained, but incorrect command execution occurs due to interference or falsification
Solution Approach 1:
The system performs preliminary authentication setup by transmitting the transaction code before command execution. This preliminary action establishes the authentication framework in advance, enabling rapid verification of command correctness without slowing down the overall transmission process
Solution Approach 2:
The patent replaces complex mechanical or procedural authentication systems with a cryptographic substitution mechanism. Using authentication codes generated through cryptographic functions allows for rapid, automated verification of command correctness, maintaining transmission speed while ensuring reliability
