CANada

Controller Area Network Automatic Defense Architecture (CANada)

CANada is a prototype architecture for improving the security of a Connected Vehicle (CV) using Hardware Security Modules (HSM) to monitor the traffic on a CAN bus. Most code in this project is related to simulating a CAN bus and the behaviour of various Engine Control Units (ECU) and HSMs.

For the most consistent experience we recommend running the simulations in either Linux or MacOS.

Getting Started

Useful Tools

• conda - https://conda.io/miniconda.html (useful in managing multiple python environments, be sure to install Python 3.7 version)

Conda

In this repository there is an environment.yml file that contains information about the dependencies required by this project. It also specifies tso as the name of the environment.

Creating a New Environment in Conda From an environment.yml File

conda env create -f environment.yml

Switching Environments Created Using Conda

MacOS/Linux

source activate can

Windows

activate can

Running Trials to Gather Metrics

In order to run several iterations of the system to gather metrics about the behaviour, run the following command where N_TRIALS is the integer number of trials to run and TRIAL_DURATION is the duration of the trial in seconds:

python run_trials.py [N_TRIALS] [TRIAL_DURATION]

Running the Simulation

The simulations will run until the process is killed by the user. To do so press ctrl+c.

In order to run each of the simulations, execute the following:

Frequency Moderation Security Simulation

python freq_simulation.py

Authentication Security Simulation

python auth_simulation.py

Intrusion Detection Simulation

python intrusion_simulation.py
