Development of a secure bootloader for encrypted OTA update via BLE.

The bootloader has been developed in C in order to allow the OTA update of the Texas Instrument CC2640R2F, securely with an encrypted firmware image.

The client controls the private keys and thanks to encryption techniques it is not possible to disassemble the firmware from it’s publicly shared binary.

This secure bootloader is loaded on a genuine product and third parties cannot use the encrypted application image thus protecting the Intellectual Property from unwanted copies.
