SECURE REMOTE SENSOR SIMULATOR FOR HEAVY VEHICLE ELECTRONIC CONTROL UNITS
Abstract: Heavy Vehicle Event Data Recorders (HVEDRs) have the capability to record crash-related data and are valuable tools for traffic crash investigators. The data extracted from HVEDRs contain information to help reconstruct the driver's behaviors and determine the events leading to a crash. Data extraction is commonly performed using diagnostic tools when the electronic control unit (ECU) with the HVEDR is available on the vehicle's network. In the cases where the electrical system of the vehicle is compromised, the ECU is often removed and connected to a harness for power and communications. These harnesses are not designed to preserve fault codes or diagnostic trouble codes. This can result in overwriting data related to a particular crash event.
This thesis describes the open-source hardware and software design of the remote sensor simulator which is used in creating a fault-free environment for a bench download reducing the chance of any alteration of the original data inside the HVEDRs. Also, the thesis focuses on a process to increase the security posture of the embedded IoT devices wherein it utilizes hardware security modules to offload cryptography operations. The device also securely connects to a cloud infrastructure using Transport layer security (TLS), enabling investigators to operate these devices remotely using a web-based graphical user interface.
