Seminar Title

Black-box Adversarial Attacks for Deep Driving Maneuver Classification Model

Seminar Abstract

In a connected autonomous vehicle (CAV) scenario, each vehicle utilizes an onboard deep neural network (DNN) model to understand its received time-series driving signals (e.g., speed, brake status) from its nearby vehicles, and then takes necessary actions to increase traffic safety and roadway efficiency.

In the scenario, an attacker may launch an adversarial attack, in which the attacker adds unnoticeable perturbation to the actual driving signals to fool the DNN model inside a victim vehicle to output a misclassified class to cause traffic congestion and/or accidents. Such an attack must be generated in near real-time and the adversarial perturbation is not noticeable in the current traffic context. However, previously proposed adversarial attacks fail to meet these requirements. To handle these challenges, we propose black-box adversarial attacks for time-series DNN models in the CAV scenarios. By analyzing real driving datasets, we observe driving signal patterns and features. Then, based on our observations, we design offline perturbations, which are used as a starting point in the online perturbation determination to generate the attacks. Our extensive experimental studies using two real driving datasets show that our proposed adversarial attacks require much shorter generation time and less perturbation amount than existing adversarial attacks.
