Research Project Experiences

Jan 2017
Dec 2017
Comprehensive Security Analysis of Tesla Model S
Participation: Overall project management and administration. Explored the possibility of sensor attacks against sensors mounted on Tesla Model S 90D: e.g. GPS and Camera. Successfully induced abrupt braking and disabled upper speed limit during autopilot. Successfully incapacitated autonomous emergency braking feature by blinding attacks against the mounted camera module.
Jan 2017
Dec 2017
Development of Information-leakage Prevention and Drone ID Management Technologies for Safe Drone Services
Participation: Explored the possibility of sensor attacks against drone-mounted sensors: e.g. lidar, ultrasonic sensors, and vision sensors.
Jul 2016
Jun 2017
Security Analysis of Core Sensing Modules for Smart Vehicles
Participation: Overall project management and administration. Sensor spoofing & blinding attacks against one of Velodyne’s vehicular lidar models. Successfully induced multiple fake points at a controllable location by spoofing, and incapacitated the victim lidar from sensing an obejct by blinding. Invisible blinding attacks against one of Mobileye’s vehicular vision sensor. Succeeded in DoSing the victim vision sensor remotely with laser whose wavelength is invisible to human eye. Practical mitigative measures against discovered attacks were also studied and devised.
Oct 2014
Dec 2016
Development of Gateway for Safe IoT Networking
Participation: Optical channel sensor spoofing attack inducing over-infusion of medical fluids against the drop sensor of a off-the-shelf medical infusion pump.
Mar 2014
Feb 2015
Safe & Reliable Vehicular Environment Perception System for Personal Digital Electric Vehicles
Participation: Survey on the possibility of sensor spoofing attacks against vehicular radar modules. Showed by simulation that attackers can easily access and affect the victim radar’s measurement by “phase-code brute force”. In the simulation the victim radar was assumed to use Phase-Coded Modulation scheme, which is quite effective to suppressing accidental inter-radar interferences.
Mar 2014
Dec 2014
Safe Sensing & Networking for Smart Mobile Health-care
Participation: Sensor spoofing attack inducing fake heartbeat against optical heartbeat sensor on Samsung smart watch.
Aug 2013
Dec 2013
EEWS Smart Grid Project Planning
Participation: Survey on intrusion detection/protection systems in smart grid networks. Survey on possibility of hardware tempering and sensor attacks against smart meters’ electricity usage measurement subsystems.
