Information Aging through Queues: A Mutual Information Perspective
Yin Sun, Benjamin Cyr
In this paper, we propose a new measure for the freshness of information, which uses the mutual information between the real-time source value and the delivered samples at the rece…
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…
Adversarial Sensor Attack on LiDAR-based Perception in Autonomous Driving
Yulong Cao, Chaowei Xiao, Benjamin Cyr +6
In Autonomous Vehicles (AVs), one fundamental pillar is perception, which leverages sensors like cameras and LiDARs (Light Detection and Ranging) to understand the driving environm…
Sampling for Data Freshness Optimization: Non-linear Age Functions
Yin Sun, Benjamin Cyr
In this paper, we study how to take samples at a data source for improving the freshness of received data samples at a remote receiver. We use non-linear functions of the age of in…
