🌟 Can You Trust Autonomous Vehicles: Contactless Attacks Against Sensors of Self-driving Vehicles
As autonomous vehicles become increasingly prevalent, ensuring their safety and trustworthiness is paramount. This blog post delves into the security of autonomous vehicle sensors, highlighting potential vulnerabilities and proposing solutions to enhance their resilience. Our research investigates contactless attacks against key sensors and evaluates their impact on the functionality of self-driving cars.
📚 Abstract
Context
To improve road safety and driving experiences, autonomous vehicles have emerged as a promising technology. However, before they can be widely adopted, the trustworthiness of these vehicles must be thoroughly examined.
Research Problem
Despite their advanced safety features, the sensors that guide autonomous vehicles—such as millimeter-wave radars, ultrasonic sensors, and forward-looking cameras—are susceptible to various attacks. This study examines the security of these sensors and investigates their trustworthiness.
Study Design
Our work focuses on sensors used to guide autonomous vehicles, specifically investigating millimeter-wave radars, ultrasonic sensors, and forward-looking cameras.
Major Findings
Using off-the-shelf hardware, we were able to perform jamming and spoofing attacks, causing the Tesla’s sensors to malfunction or become "blind."
Solutions and Conclusions
To mitigate these issues, we propose both software and hardware countermeasures designed to improve sensor resilience against these attacks.
🔍 Introduction
Present the Topic and Context
Autonomous vehicles promise to revolutionize road safety and driving experiences. However, the security and reliability of the sensors guiding these vehicles need thorough examination to ensure widespread adoption.
Research Gap
While there has been significant progress in autonomous vehicle technology, there is a research gap concerning the vulnerabilities of their sensors to external attacks.
Purpose of the Study
Our study aims to investigate the security of autonomous vehicle sensors, identify potential vulnerabilities, and propose solutions to enhance their resilience.
Methodology and Approach
We conducted experiments on millimeter-wave radars, ultrasonic sensors, and forward-looking cameras to assess their susceptibility to jamming and spoofing attacks.

🚨 Threat Model
Description of the Threat
We identified several threat vectors, including jamming and spoofing attacks, that can compromise the functionality of autonomous vehicle sensors.
Attacker Objectives and Capabilities
Attackers aim to disrupt sensor readings, causing the vehicle to malfunction or misinterpret its surroundings.
Assumptions and Limitations
Our threat model assumes attackers have access to basic hardware tools and can operate within the vicinity of the target vehicle.
Potential Impact
Compromised sensors can lead to incorrect decisions by the autonomous vehicle, potentially causing accidents or operational failures.
🔍 Evaluation
Research Questions and Metelons
We evaluated the sensors' vulnerability to various attacks, using established metelons to compare results and assess the impact on sensor performance.
Methodology
Our evaluation included detailed experiments on ultrasonic sensors, millimeter-wave radars, and forward-looking cameras.
Results
We found that a significant percentage of sensors could be compromised through jamming and spoofing, leading to incorrect measurements and potential system failures.
🛠️ Methodology
