### AI overview

This article explains how to exercise ESP32-C3 security features under QEMU before deploying them to real hardware. It describes the risks of irreversible eFuse programming, QEMU's ESP32-C3 system emulation and firmware compatibility, and workflows for testing security configurations.

### Source excerpt

Overview# ESP32 series of SoCs supports multiple security features like trusted boot, flash encryption, secure storage etc. There are also dedicated peripherals to support use-cases like HMAC and digital signature. For most of these features the eFuse storage in the ESP32-C3 is responsible for storing the private keys and also the configuration bits. eFuse memory is one time programmable and hence care must be taken whilst enabling the security features.

### AI overview

Espressif introduces ESP Privilege Separation, a framework that divides ESP-IDF firmware into protected and user applications with isolated execution environments, system calls, and configurable memory and peripheral access. The framework targets ESP32-C3 and is intended to provide privilege separation for microcontroller applications.

### Source excerpt

Typically, applications on microcontrollers (MCU) are developed as monolithic firmware. We have been discussing on achieving "user-kernel" separation with appropriate execution privileges, like general purpose OS, on MCUs. The crux of this was to make the end application development easier without worrying about the underlying changes in the system, like how applications on desktop/mobile phones are developed: the underlying operating system handles the critical functionalities, and the end...

### AI overview

This comparison examines memory availability in ESP32 and ESP32-C3. It describes ESP32-C3 memory-management changes, including dynamic IRAM-DRAM allocation and different Bluetooth memory handling, and states that ESP32-C3 can provide better or equivalent memory headroom for various embedded application use cases.

### Source excerpt

Espressif launched ESP32-C3 at the end of 2020. It's very well received and now it's already in the mass production state. ESP32-C3 provides Wi-Fi and Bluetooth LE connectivity for applications in the most cost-effective way. For the users of ESP32 who use it for Wi-Fi and/or BLE connectivity, ESP32-C3 is a possible upgrade option provided other requirements match. So let's first take a look at the comparison of ESP32 and ESP32-C3 from that perspective.
