wolfSSL is pleased to announce the first ever release of wolfBoot!
wolfBoot v1.0 release page: https://github.com/wolfSSL/wolfBoot/releases/tag/v1.0
wolfBoot is a secure bootloader that leverages wolfSSL's underlying wolfCrypt module to provide signature authentication for the running firmware.
The role of a secure bootloader is to effectively prevent the loading of malicious or unauthorized firmware on the target. Additionally, wolfBoot provides a fail-safe update mechanism, that can be interrupted at any time, and resumed at next boot.
wolfBoot is designed to be a portable, OS-agnostic, secure bootloader solution for all 32-bit microcontrollers, relying on wolfCrypt for firmware authentication.
Due to its minimalist design and the tiny Hardware Abstraction Layer (HAL) API, wolfBoot is completely independent of any OS or bare-metal application, and can be easily ported and integrated into existing embedded software solutions.
wolfBoot provides the basis for secure firmware update (OTA) management at boot time, cutting down the development effort needed to implement and validate the required mechanisms to handle the updates. It reduces the development effort to just receiving the image using a secure channel within the application/OS. We recommend using wolfSSL to encrypt the firmware transfer over TLS, to avoid eavesdropping. Once the image is transferred and stored into the update partition, wolfBoot takes care of the update procedure at the next boot.
Remote updates that would lead to a faulty firmware are automatically reverted by wolfBoot after the first 'test' boot, by restoring the original firmware image whenever the update has failed to boot properly. This mechanism protects the target device from accidental updates on the field.
