I wanted to close my investigation by targeting the two major security features: Secure BootFlash Encryption My final goal is to achieve a PERSISTENT

The ESP32-D0WD-V3 chip has checks in ROM which prevent fault injection attack. This chip and related modules will be available in Q4 2019. More information about ESP32-D0WD-V3 will be released soon.

Security researchers have recently described a fault injection attack on ESP32, which may result in some security compromise and unintended disclosure of information. However, ESP32’s security design remains safe for the vast majority of our products. Here’s how.

ESP32-C3 is a single-core Wi-Fi and Bluetooth LE 5.0 microcontroller SoC, based on the open-source RISC-V architecture. It strikes the right balance of power, I/O capabilities and security, thus offering the optimal cost-effective solution for connected devices. The availability of Wi-Fi and Bluetooth LE 5.0 connectivity not only makes the device configuration easy, but it also facilitates variety of use-cases based on dual connectivity.
