Trick or Heat? Manipulating Critical Temperature-Based Control Systems Using Rectification Attacks
Yazhou Tu, Sara Rampazzi, Bin Hao +3
Temperature sensing and control systems are widely used in the closed-loop control of critical processes such as maintaining the thermal stability of patients, or in alarm systems…
Safety, Security, and Privacy Threats Posed by Accelerating Trends in the Internet of Things
Kevin Fu, Tadayoshi Kohno, Daniel Lopresti +5
The Internet of Things (IoT) is already transforming industries, cities, and homes. The economic value of this transformation across all industries is estimated to be trillions of…
Light Commands: Laser-Based Audio Injection Attacks on Voice-Controllable Systems
Takeshi Sugawara, Benjamin Cyr, Sara Rampazzi +2
We propose a new class of signal injection attacks on microphones by physically converting light to sound. We show how an attacker can inject arbitrary audio signals to a target mi…
Capability-Aware Shared Hypernetworks for Flexible Heterogeneous Multi-Robot Coordination
Kevin Fu, Shalin Anand Jain, Pierce Howell +1
Recent advances have enabled heterogeneous multi-robot teams to learn complex and effective coordination skills. However, existing neural architectures that support heterogeneous t…
Systems Computing Challenges in the Internet of Things
Rajeev Alur, Emery Berger, Ann W. Drobnis +10
A recent McKinsey report estimates the economic impact of the Internet of Things (IoT) to be between 11 trillion dollars by 20251 . IoT has the potential to have a profoun…
Side Eye: Characterizing the Limits of POV Acoustic Eavesdropping from Smartphone Cameras with Rolling Shutters and Movable Lenses
Yan Long, Pirouz Naghavi, Blas Kojusner +3
Our research discovers how the rolling shutter and movable lens structures widely found in smartphone cameras modulate structure-borne sounds onto camera images, creating a point-o…
Touchtone leakage attacks via smartphone sensors: mitigation without hardware modification
Connor Bolton, Yan Long, Jun Han +2
Smartphone motion sensors provide a concealed mechanism for eavesdropping on acoustic information, like touchtones, emitted by a device. Eavesdropping on touchtones exposes credit…
ARMOUR US: Android Runtime Zero-permission Sensor Usage Monitoring from User Space
Yan Long, Jiancong Cui, Yuqing Yang +3
This work investigates how to monitor access to Android zero-permission sensors which could cause privacy leakage to users. Moreover, monitoring such sensitive access allows securi…
Side Auth: Synthesizing Virtual Sensors for Authentication
Yan Long, Kevin Fu
While the embedded security research community aims to protect systems by reducing analog sensor side channels, our work argues that sensor side channels can be beneficial to defen…
Private Eye: On the Limits of Textual Screen Peeking via Eyeglass Reflections in Video Conferencing
Yan Long, Chen Yan, Shilin Xiao +3
Using mathematical modeling and human subjects experiments, this research explores the extent to which emerging webcams might leak recognizable textual and graphical information gl…
Generalization of Heterogeneous Multi-Robot Policies via Awareness and Communication of Capabilities
Pierce Howell, Max Rudolph, Reza Torbati +2
Recent advances in multi-agent reinforcement learning (MARL) are enabling impressive coordination in heterogeneous multi-robot teams. However, existing approaches often overlook th…
