Device Secure Boot – IoT Security Foundation
The bootloader code is developed using a secure development process and then a cryptographic hash of it is digitally signed with the manufacturer's private key. Whenever bootloader firmware is to be installed on the device, the hash signature is checked against the embedded public key on the device to confirm that it is a genuine hash value

Understanding ESP32's Security Features | by Kedar Sovani
May 31, 2018 · Flash Encryption. The flash encryption support ensures that any application firmware, that is stored in the flash of the ESP32, stays encrypted. This allows manufacturers to ship encrypted firmware in their devices. When flash encryption is enabled, all memory-mapped read accesses to flash are transparently, and at-runtime, decrypted.

Jetson nano secure boot with encrypted filesystem - Jetson
Oct 15, 2021 · Hi, Is it possible to use secure boot with an encrypted hard-drive where the hard-drive decryption key is contained in the bootloader (or somewhere secure). After reading the docs it seems possible but I am not familiar with kernel/bootloader code. How would I go about doing this? I am currently using an external MCU with encrypted flash to store keys but it would be …

Flash Encryption — ESP-IDF Programming Guide documentation
Flash Encryption is a feature for encrypting the contents of the ESP32's attached SPI flash. When flash encryption is enabled, physical readout of the SPI flash is not sufficient to recover most flash contents. Flash Encryption is separate from the Secure Boot feature, and you can use flash encryption without enabling secure boot.
