Firmware Over-The-Air (FOTA)

Secure the updates of software-defined vehicles

Vehicle technology, as with any other new advancement, has evolved over time. Modern vehicles with approximately 100 Electronic Control Units (ECUs) and over 100 million lines of software code are running interconnected on roads. Such vehicles with complex electronics and software need continuous updates to ensure vehicle performance and safety.

Updating the ECU firmware while the vehicle is running is possible with over-the-air updates. However, compromise in one ECU during the update allows the attackers full access to other ECUs.

Firmware over-the-air not only enables the secure updating of firmware and software but also reduces the time and resources consumed for manual updates. FOTA updates involve firmware bug repairs, increasing the functionality of the vehicle ECU, and replacing outdated firmware versions with updated versions (for either fixing an issue or adding a new software feature).


Applications for Firmware Over-The-Air (FOTA)
