Project Overview

We are working to encypt messages on the CAN bus to increase vehicle safety and security. Within the network, bridges have to handle many incoming messages and reroute them towards the proper end destination. Some messages will need to be sent to another bridge, which is where we will be using CAN FD frames to send groupings of these messages from one bridge to another. We are fosued on encrypting these messages to increase the availability, integrity, and authenticity of bridge to bridge communication.

As the digital era grows, there are more vulnerabilities found in different products we use in our day to day lives. In 2015 it was publicized that a wireless attack can happen on mobile vehicles that are susceptible to a vulnerability in Chrysler's UConnect app for specific trim levels of their vehicles. The vulnerability allowed hackers to gain "admin level" privileges and remotely control certain electronic control units of the vehicle, which could be examples of, but not limited to: the lights, radio, steering wheel, brakes, transmission and AC/ heat unit. This dire vulnerability is hiding in a world of unsuspecting drivers, so it's our mission to make it no longer a worry. Our goal with this project is to deny the ability of a wired or wireless attack on a CAN bus network, so that people driving vehicles, pedestrians, auto-manufacturers have peace of mind in their day to day lives on being physically harmed from one of these attacks.
