Over-the-air (OTA) firmware update is available in some systems such as mobile networks. Security plays a vital role to ensure that the firmware update process is successful despite possible threats against it. Therefore mobile devices may be useful to support the OTA firmware update process for other devices such as those used for automotive applications. Using a mobile device as a tool can offer added security features as well as giving flexibility to the process. Automotive security is of high importance as it is critically related to the safety and reliability of the vehicle. We propose a secure OTA firmware update (FOTA) protocol to offer flexibility to the firmware update process, while meeting the required security requirements. The protocol was formally analysed using Scyther and CasperFDR and no known attack was found.
