Modern vehicles today are beginning to implement smartphone control as an alternative to car keys. However, auto manufacturers have no common standard in implementing smartphone control. Project Portunus creates a secure, plug-and-play implementation of smartphone control using Allthenticate’s suite of hardware and software encryption tools. The project utilizes a minimally based design using a Raspberry Pi to connect to the OBD II port and communicate with the vehicle via the CAN bus. The module will perform necessary functions such as locking and unlocking doors, tracking vehicle location, and turning lights on and off. The final device works over bluetooth with Allthenticate’s mobile app for control.
