Developing a mixed-critical AUTOSAR Adaptive ECU with Safety & Security by Design
At the EW19-Conference Dr. Sergey Tverdyshev (Director Research & Technology, SYSGO) presented a mixed-critical AUTOSAR Adaptive system, both at application and OS level. He presented a safe and secure architecture with built in spatial and temporal separation between AUTOSAR Adaptive applications to enable safe and secure deployment. He showed the usage of mechanism enabling by AUTOSAR Adaptive required dynamics, e.g. separating startup phase and runtime, scheduling with fixed time windows (as opposed to purely priority-based approaches), pinning of processes on CPU cores, pre-defined access to files and service discovery, execution of only authenticated code and certain APIs.
The next evolutionary steps in the automobile are: Automatic driving, Car-2-X and dynamic deployment of apps. This means strong performance, high reliability and availability, secure over-the-air update and security by design. AUTOSAR Adaptive targets to provide such a required flexibility. This flexibility however raises the bar for the integration approaches on both sides: safety and security.
