CycloneBOOT
Secure Bootloader for ARM Cortex-M MCU

CycloneBOOT is a secure bootloader targeting 32-bit microcontrollers. You will be able to update your firmware securely as CycloneBOOT employs several encryption algorithms to make sure that your firmware is always under lock and key.

CycloneBOOT is protocol agnostic, meaning that a firmware update can be performed using various physical media (Ethernet LAN, Wi-Fi, Cellular Modem, USB, UART, SD card...). In any case, during the firmware update process, CycloneBOOT rigorously verifies the integrity of each data packet.

CycloneBOOT is available either as open source (GPLv2 license) or under a royalty-free commercial license (non-GPL license). We also propose an evaluation license (90-day license in source form) with technical support for an easier onboarding and effective evaluation of our software.

Main Features

• Secure bootloader for 32-bit MCUs
• Can be integrated in client or server operation
• Provides In-Application Programming (IAP) support
• Support for dual-bank flash, single-bank flash and external flash
• Can run alongside a RTOS or in bare metal
• Support for encrypted firmware (using AES-CBC)
• Firmware image with signature (using RSA, ECDSA), authenticity (using HMAC), or integrity verification (using CRC32, SHA-1, MD5, SHA-256 or SHA-512)
• Fallback support (Backup current firmware and restore it if required)
• Anti-rollback support (Prevent rolling-back to a known faulty firmware version)
• PC utility running on Windows or Linux to build the firmware image (can encrypt the firmware and compute an integrity tag, an authentication tag, or a signature)
