Bosch says it is securely updating cars over the air
Bosch says it has developed all the features required for wireless updates in-house. They range from the control units and in-car communication infrastructure to modern encryption technologies and the Bosch IoT cloud. “In a few years from now, automatic software updates will be possible in every new car,” said Dr. Markus Heyn, a member of the Bosch board of management. “Wireless over-the-air updates are extremely convenient for drivers. In addition, Bosch is making these online updates secure and fast.”
The company says data security is ensured by the latest encryption technologies developed at the Bosch subsidiary Escrypt. A complex security architecture with end-to-end encryption protects the data transmission against unauthorized access. At the car-cloud interfaces, secure protocols and filters act like a firewall to ward off any hacking attempts. To ensure that over-the air software updates are, secure, fast, and reliable, Bosch says it uses fast update technologies such as delta and compression mechanisms. These accelerate the update process and reduce cost, since the data volume for the transmission remains low. One further security measure is to transmit the updates in sequences. If problems occur, the update process can be stopped and adjusted. The technology at the heart of these over-the air updates is the Bosch Automotive Cloud Suite.
“Cars are driven for 15 years or more. Over-the-air software updates are Bosch’s contribution to keeping vehicle software constantly up to date, without having to visit the repair shop,” said Heyn.
