Introduction
Unmanned aerial vehicles (UAVs) have evolved from specialized military assets to ubiquitous commercial platforms deployed across logistics, agriculture, surveillance, and disaster response. However, this proliferation has exposed a critical vulnerability: autonomous aerial systems are increasingly susceptible to sophisticated cyber-physical attacks—including GPS spoofing, adversarial AI manipulations, and communication protocol exploits—that can hijack drones, disrupt operations, or leak sensitive data. The Morgan State University DEPA Research Lab’s $25,000 award from the IEEE Aerospace and Electronic Systems Society (AESS) Cybersecurity Challenge – Phase 2 recognizes a groundbreaking solution: a lightweight onboard AI-driven cybersecurity framework capable of detecting, analyzing, and responding to these threats in real time, all while operating within the severe computational and power constraints of UAV platforms.

You Should Know
1. The Cyber-Physical Threat Landscape for UAV Systems
Modern UAVs are complex cyber-physical systems integrating GPS receivers, inertial measurement units (IMUs), wireless communication links (Wi-Fi, cellular, or dedicated RF), onboard cameras, and AI-powered flight controllers. Each of these components presents an attack surface. GPS spoofing can feed false location data to the autopilot, causing the drone to veer off course or crash. Adversarial AI attacks manipulate the machine learning models that govern navigation and object tracking—researchers have demonstrated that an ordinary umbrella can fool an autonomous target-tracking drone. Model poisoning attacks embed hidden triggers during the AI training phase, causing failures under specific conditions. Communication protocol vulnerabilities enable hijacking, data exfiltration, or denial-of-service.
The Morgan State team’s framework addresses these threats through three integrated capabilities: intelligent anomaly detection that identifies deviations from expected behavior, adaptive threat awareness that evolves with emerging attack patterns, and safe mission response mechanisms that execute defensive actions without compromising flight safety. This multi-layered approach aligns with the emerging paradigm of using physical state consistency as an authenticity proof for cyber traffic—if sensor data shows sudden altitude fluctuations inconsistent with commanded inputs, an attack is likely underway.
Step-by-Step Guide: UAV Telemetry Monitoring for Anomaly Detection (Linux)
To detect anomalies in UAV telemetry, you can set up a real-time monitoring pipeline using open-source tools. Below is a practical workflow for analyzing MAVLink telemetry streams.
1. Install MAVProxy and necessary dependencies sudo apt-get update sudo apt-get install python3-pip screen pip3 install mavproxy pymavlink <ol> <li>Connect to the UAV telemetry stream (replace /dev/ttyUSB0 with your connection) mavproxy.py --master=/dev/ttyUSB0 --baudrate=57600 --out=127.0.0.1:14550</p></li> <li><p>In a separate terminal, capture telemetry to a log file for analysis mavproxy.py --master=127.0.0.1:14550 --cmd="log create telemetry_log"</p></li> <li><p>Monitor GPS and IMU data for anomalies in real time mavproxy.py --master=127.0.0.1:14550 --cmd="status" --cmd="watch gps"
For Windows environments, use Mission Planner’s telemetry logging feature or WSL (Windows Subsystem for Linux) to run the above commands. Additionally, you can analyze network traffic to detect spoofing attempts:
Windows: Capture Wi-Fi traffic from UAV ground control station netsh wlan show networks mode=bssid Use Wireshark with filter: udp.port == 14550 or udp.port == 14551
2. Lightweight AI Architectures for Onboard Deployment
The defining constraint of onboard UAV cybersecurity is resource limitation. A typical drone flight controller has limited CPU, minimal RAM (often under 512 MB), and strict power budgets measured in milliwatts. The Morgan State team’s framework leverages lightweight AI models that achieve high detection accuracy with minimal computational overhead. Recent research demonstrates that Temporal-Spatial Lightweight Transformer networks (TSLT-1et) achieve 99.99% accuracy in multiclass attack detection while maintaining a memory footprint of just 0.04 MB and 9,722 trainable parameters. Similarly, BPBiLSTM-IDS frameworks provide scalable, real-time intrusion detection with inference times as low as 0.0023 seconds per sample. Hybrid CNN-GRU autoencoders with knowledge distillation further reduce model size while preserving detection capabilities.
The key insight is that anomaly detection on UAVs does not require large, general-purpose models. Instead, specialized architectures—Mamba-KAN-Liquid hybrid models, for instance—achieve detection rates exceeding 95% across six UAV cyberattack types (GPS spoofing, replay attacks, DoS, etc.) with only 2.5 million parameters and 96 MB memory. These models are trained on telemetry datasets (attitude, velocity, GPS coordinates, battery status) and learn the normal operational envelope; any deviation triggers an alert.
Step-by-Step Guide: Deploying a Lightweight IDS on a UAV Companion Computer
This example uses a Raspberry Pi (or similar ARM-based single-board computer) as a companion computer running a pre-trained anomaly detection model.
1. Set up Python virtual environment with TensorFlow Lite
python3 -m venv uav_ids
source uav_ids/bin/activate
pip install tensorflow==2.15.0 numpy pandas scikit-learn pymavlink
<ol>
<li>Load a pre-trained lightweight model (example: TSLT-1et or custom CNN)
Assume model file is 'uav_anomaly_model.tflite'
import tensorflow as tf
import numpy as np</li>
</ol>
interpreter = tf.lite.Interpreter(model_path="uav_anomaly_model.tflite")
interpreter.allocate_tensors()
<ol>
<li>Define function to preprocess MAVLink telemetry into model input
def preprocess_telemetry(attitude, gps, velocity, battery):
Normalize and format as expected by the model
features = np.array([attitude.roll, attitude.pitch, attitude.yaw,
gps.lat, gps.lon, gps.alt,
velocity.x, velocity.y, velocity.z,
battery.voltage, battery.current]).reshape(1, -1)
return features.astype(np.float32)</p></li>
<li><p>Run inference on each telemetry frame
input_details = interpreter.get_input_details()
output_details = interpreter.get_output_details()
In your telemetry loop:
features = preprocess_telemetry(attitude, gps, velocity, battery)
interpreter.set_tensor(input_details[bash]['index'], features)
interpreter.invoke()
anomaly_score = interpreter.get_tensor(output_details[bash]['index'])
if anomaly_score > 0.85: Threshold
print("ANOMALY DETECTED: Potential cyber-physical attack")
Trigger mitigation: switch to failsafe mode, alert ground station
3. Real-Time Threat Response and Mission Resilience
Detection alone is insufficient; a cyber-resilient UAV must respond intelligently to threats while maintaining mission integrity. The Morgan State framework incorporates safe mission response mechanisms that balance security actions with operational requirements. For instance, upon detecting GPS spoofing, the system might transition from GPS-dependent navigation to visual-inertial odometry, or execute a pre-programmed return-to-home procedure. For adversarial AI attacks targeting the perception system, the framework could switch to a backup model or fallback to basic obstacle avoidance.
The IEEE AESS Cybersecurity Challenge emphasizes the integration of AI and cybersecurity in aerospace systems. The Morgan team’s approach aligns with this vision by enabling adaptive threat awareness—the system continuously learns from new attack patterns and updates its detection models without requiring ground-based retraining. This is particularly valuable for UAV swarms, where a single compromised node could propagate malicious behavior across the fleet.
Step-by-Step Guide: Implementing a Response Mechanism in ArduPilot/PX4
1. In ArduPilot, create a custom failsafe trigger based on anomaly detection output
Edit ardupilot/ArduCopter/failsafe.cpp to include:
void Failsafe::check_uav_anomaly(float anomaly_score) {
if (anomaly_score > ANOMALY_THRESHOLD) {
gcs().send_text(MAV_SEVERITY_CRITICAL, "UAV Anomaly detected!");
set_failsafe(FAILSAFE_ACTION_LAND);
}
}
<ol>
<li>For PX4, use the uORB messaging system to publish anomaly events
In your companion computer code:
import os
os.system("commander control mode --manual") Switch to manual control
os.system("commander arm") Prepare for landing
4. Network Security and Ground Control Station Hardening
UAV cybersecurity extends beyond the aircraft itself. Ground control stations (GCS), telemetry links, and cloud-based mission planning systems are equally vulnerable. Attackers can intercept and manipulate MAVLink messages, inject false GPS coordinates, or exploit vulnerabilities in GCS software. The Morgan State framework addresses the end-to-end security chain, ensuring that detection capabilities are distributed across the UAV-GCS-cloud continuum.
Step-by-Step Guide: Securing MAVLink Telemetry with Encryption
1. Use MAVLink 2.0's signing feature to authenticate messages In MAVProxy: mavproxy.py --master=/dev/ttyUSB0 --baudrate=57600 --signing-key=YOUR_SECRET_KEY <ol> <li>Set up a VPN tunnel between UAV and GCS (WireGuard recommended) On the UAV companion computer: sudo apt-get install wireguard wg genkey | tee privatekey | wg pubkey > publickey sudo nano /etc/wireguard/wg0.conf Add configuration with GCS endpoint</p></li> <li><p>On Windows GCS, use Mission Planner with TLS-enabled connections: Connection > TCP > Port 5762 (enable TLS)
5. AI Model Security: Defending Against Adversarial Attacks
A critical yet often overlooked vulnerability is the AI model itself. Adversarial examples—subtly perturbed inputs that cause misclassification—can fool perception systems, causing drones to misidentify obstacles or targets. Model poisoning attacks during the training phase can embed backdoors that activate under specific conditions. The Morgan State team’s research addresses these challenges by incorporating robust training techniques and runtime anomaly detection that flags inputs deviating from the training distribution.
Step-by-Step Guide: Adversarial Robustness Testing
Using the Foolbox library to test model robustness
import foolbox as fb
import tensorflow as tf
Load your UAV perception model
model = tf.keras.models.load_model('uav_perception_model.h5')
fmodel = fb.TensorFlowModel(model, bounds=(0, 255))
Generate adversarial examples using FGSM
attack = fb.attacks.LinfFastGradientAttack()
epsilons = [0.0, 0.001, 0.01, 0.03, 0.1, 0.3, 0.5, 1.0]
robustness = fb.utils.accuracy(fmodel, images, labels, epsilons=epsilons)
print(f"Model robustness: {robustness}")
If robustness is poor, implement adversarial training:
