This repo contains a firmware for IoT devices based on ESP32 platform. The project implements a software-based SRAM PUF (Physically Unclonable Function) that can be used to generate a unique value. This value can then be utilized to implement security primitives. The project aims to provide a secure and reliable way of storing and transmitting data in IoT devices.

This section should provide instructions for other developers to
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
The first time you clone this repo, or when the ESP IDF version is changed, you need to install dependencies with following command:
esp-idf/install.sh esp32
Each time you want to open a terminal you have to use this command to export the required environment variabled:
. esp-idf/export.sh
Build the project by running:
idf.py build
Connect your ESP32 board to the computer and check under what serial port the board is visible. Serial ports have the following patterns in their names:
- Linux: starting with
/dev/tty - macOS: starting with
/dev/cu.
Flash the binaries onto your ESP32 board by running:
idf.py -p PORT flash
Replace PORT with your ESP32 board’s serial port name.
To run the serial monitor (IDF monitor) you can do as follow:
idf.py -p PORT monitor
To exit IDF monitor use the shortcut Ctrl+].
