How Continental managed to test a large safety module with 18,000 lines of code (LoC) within only one week.

Developing Secure Infotainment Systems Faster

1. Realizing Modern Security Tests in An Embedded Automotive Architecture

Continentals HMI business unit develops embedded systems and solutions for the human-machine interface of modern road vehicles. For example, display solutions, head-up displays and cockpit high-performance computers. HMI makes processing and managing information simple, intuitive, and reliable.

Infotainment systems in modern vehicles usually communicate with a whole range of external embedded sensors. These dependencies add an additional layer of complexity for security testing, as they typically require plenty of manual effort.

2. Complying With ISO 21434/UNECE WP.29

As a result of the new ISO/SAE 21434 and UNECE WP.29, many car producers (OEMs) are extending their software testing activities. The standard holds regulations for software devices within vehicles, along with their connectivity to external systems.

Fuzzing Embedded Systems With Dependencies

The CI fuzz testing platform makes it possible to apply modern fuzz testing approaches in an early stage of the software development process. This has automated and simplified the entire testing process because it enabled the developers to perform security tests on their own modules and to fix critical bugs right away.

The CI Fuzz testing platform also enabled the developers to mock their hardware with fuzz data. By applying feedback-based fuzzing many developers at Continental are now able to protect their software against edge cases and unexpected behaviors. For example, if a sensor should send unusual or erroneous inputs.
