Updates over the air

Updates over the air

Wireless internet enables connectivity that doesn’t require physical presence. With software or firmware updates over the air (SOTA/ FOTA), Bosch can now ensure that vehicles are always state of the art.

Direct from the cloud – Updating a car as easily as a smartphone

Regular security updates close vulnerabilities and protect against hacker attacks.
Over the air updates avoid recalls and reduce repair shop visits.
New vehicle system functions are easy to activate and test.

New vehicle system functions are easy to activate and test.

SOTA and FOTA secure mobility by allowing the innovative technology to simply and reliably optimize the vehicle without requiring a visit to the repair shop. It also makes new or improved functions available directly to the driver.

With its comprehensive systems and connectivity expertise, Bosch meets all the requirements from a single source. Naturally, the Bosch IoT Cloud offers the utmost security for the data of over-the-air updates. Fast update technologies like delta and compression mechanisms accelerate the update process and reduce costs.

Over-the-air firmware or software updates

Everyone is familiar with updates to their smartphone software. It’s the same process for authorizing over-the-air firmware or software updates. The user selects a function on their smartphone or the car’s infotainment system. This request gets sent to the cloud, which, functioning much like an app store, starts the software download directly into the vehicle. The secure data transfer takes place in the background while the vehicle is in operation. Updates are then carried out only when the vehicle is in a safe state.

… complex and carefully thought
through in the background

Update process

Bosch’s connectivity expertise comes to the fore as it supports the entire process and the full range of applications. In particular thanks to the ESCRYPT automotive security solutions from the Bosch subsidiary ETAS, the software remains protected from external access during transmission. A delta algorithm ensures that only the delta package, generated from two software or firmware packages, is sent as an update. This minimizes the volume of data to be transferred. Carrying out the update in sequence is an additional security measure: if any problems arise, the update can be stopped to make adjustments.

Security at all levels

The rising connectivity of today’s vehicles is enhancing driving convenience and the driving experience enormously. At the same time, however, it increases vehicles’ vulnerability to malicious attacks. That’s why data security is at the core of Bosch’s innovative FOTA and SOTA technology.

The data transfer is shielded by a complex security architecture with end-to-end encryption. At external interfaces, secure protocols as well as filters that function like firewalls guard against every attempt to access the system.

Digital signatures aid in testing the integrity of a package, and TLS encryption protects against unauthorized access. ESCRYPT provides suitable solutions for holistic automotive security – from the security risk analysis during the development phase up to secure software updates over the air.
