Secure Download Firmware Update (DFU)

Learn how to implement a secure (OTA) firmware update with a traditional micro-controller using a Microchip secure element such as the ATECC608A. It's a simple, cost efficient yet robust security implementation that protects the key verifying the signed code comes from a legitimate source. The key remain protected leveraging the ATECC608A secure element. Both asymmetric and symmetric architectures are covered in the video.
