    Secure firmware updates (OTA)

    In the mobile communications sector software updates for smartphones via WLAN or mobile network are common practice. Now the automotive industry is discovering the benefits of remote updates, too.

updates Today‘s automobiles have an increasing number of electronic control units (ECU), which are interconnected via vehicle net-works (e.g. CAN, MOST). Moreover, software in cars is going to grow in both amount and complexity. That is why it is essential for car manufacturers to manage the software during the entire life cycle of the vehicle efficiently and above all - securely. Here automobile manufacturers are increasingly opting for remote, Over-The-Air (OTA) update technologies.
