ESP32 - IoT Device Security Workshop

This ESP32 Firmware project is the complete package that will be loaded upfront into the device.

It consists of four function modules:

• IoTMate.c – The main IoT device application

• espPerso.c – The personalization workflow, which is triggered during the first Time Boot Process

• DeviceID.c – All functions to generate key material, generate CSR, and store the Device ID in the trusted area

• TrustPlatform.c – The trusted storage area that is part of the SPIFFS file. Therefor the SPIFFFS partition has to be part of the partitiontable. The Momory is encrypted with an on-demand generated AES Key.

Note: Configuration of the default parameters is done in the idf.py menuconfig.

Prerequisites

The following prerequisites apply:

• Since the main IoT device uses an OLED Display, the Component folder with the sdd1306 package has to be included in the makefile.
• mbedtls must be added to the project. This is the core crypto library that is used.
