RIOT Summit 2024, "Reverse engineering the ESP32 Wi-Fi hardware"

Jasper Devreker, esp32-open-mac (Dekimo) Slides: http://summit.riot-os.org/2024/wp-content/uploads/sites/19/2024/09/04-1-Jasper_Devreker.pdf --- The ESP32 is a low-cost microcontroller with Wi-Fi connectivity. Currently, the Wi-Fi MAC layer of the ESP32 is closed-source. This project aims to change that: by reverse engineering the hardware registers and software, we can build a networking stack that is open-source up to the hardware, instead of having to use the proprietary Wi-Fi binary blobs. This will improve security auditability, open up the possibility for features not supported in the proprietary implementation (for example, standards-compliant mesh networking), improve interoperability and make research into Wi-Fi networks with lots of nodes more affordable. --- Jasper is a software/hardware developer at Dekimo Gent (Belgium). In his spare time, he works on projects related to hardware, security and wireless communication. --- https://summit.riot-os.org/2024
