Solution Overview

Problem

Existing methods for defending unmanned aerial vehicles (UAVs) against cyber attacks, particularly WiFi hijacking, are limited in range and specificity, as they rely on software vulnerabilities that can evolve and are not effective against unknown threats, and there is a need for a system to detect and physically respond to such attacks.

Innovation Solution

A system comprising an augmented reality headset with an antenna array that allows users to detect and locate rogue RF signals, enabling hands-free operation and response, either by physically disabling the attacker or jamming the hostile transceiver, to regain control of the UAV.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If software security measures are implemented to prevent known vulnerabilities, then security against known threats is improved, but the system remains vulnerable to unknown software vulnerabilities and requires specific solutions for each platform

Engineering Contradiction:
Improvesecurity against known threatsVSAvoidprotection against unknown threats
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system segments the defense approach into two layers: software-based protection for known vulnerabilities and hardware-based RF detection for unknown threats. The RF detector array physically separates from the software stack, allowing independent operation and detection of previously unknown attack vectors without relying on software updates or platform-specific knowledge.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary RF detection system that monitors the radio frequency environment between the attacker and the UAV. This intermediary layer detects malicious RF signals before they reach the UAV's software, providing a buffer that prevents both known and unknown vulnerabilities from being exploited.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the operational range for hijack attack is limited by UAV transmission range, then detection range is improved, but the response capability is worsened due to close-range requirement

Engineering Contradiction:
Improvedetection rangeVSAvoidresponse capability
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system extends detection beyond the traditional close-range RF environment by using an array of detectors that can triangulate and track malicious signals over greater distances. The augmented reality component adds a visual dimension to the response, allowing operators to see and respond to threats from a distance rather than requiring close physical proximity.

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

Solution Approach 2:

The patent replaces the need for close-range physical response with remote identification and response capabilities. Instead of requiring operators to physically approach and neutralize threats at close range, the system uses RF detection and visual overlay to identify and respond to threats from a safe distance.

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

3Productivity

If hands-free operation is implemented for threat response, then operator safety and response time are improved, but device complexity increases

Engineering Contradiction:
Improveresponse timeVSAvoidsystem integration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single integrated system: RF detection, signal triangulation, augmented reality display, and response guidance are combined into one cohesive platform. This integration reduces the need for multiple separate devices and simplifies the operator's workflow, allowing hands-free operation without managing multiple independent systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The augmented reality headset serves multiple functions simultaneously: displaying RF signal information, providing directional guidance to threats, enabling hands-free communication, and offering situational awareness. This multi-functionality reduces the need for additional specialized equipment while maintaining comprehensive threat response capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The system and methods described herein aids in the defense of unmanned vehicles, such as aerial vehicles, from wifi cyber attacks. Such attacks usually do not last long and in the case of many point-to-point command and control systems, the attacks originate from close proximity to the unmanned vehicle. The system and methods described herein allow a team to rapidly identify and physically respond to an adversary trying to take control of the unmanned vehicle. Another aspect of the embodiment taught herein is to allow for the location of a wifi signal in a hands-free manner by able to visualize the source of the signal using an augmented reality display coupled to an antenna array.
