ETAS and Lynx Software Technologies – Separate yet together

Innovation requires a solid foundation. Enter the automotive hypervisor from ETAS and Lynx Software Technologies, which enables the next generation of ECUs.

Connected vehicles, vehicle computers, cyber security, global distributed development, new powertrain solutions… the list of automotive innovations is quite long. But there is one thing that all these systems share in common: The need for a clear separation of application software from different sources. Only with this partition can the effort of test and coordination be handled and kept manageable. But unlike in the IT world, the specific time behavior is important as well. Take exhaust gas treatment and vehicle dynamics, for instance, where every millisecond counts. Software updates cannot be allowed to interfere with this. And, what is more, a strict separation makes it much more difficult for hackers.

This is precisely why ETAS has added the LynxSecure Separation Kernel Hypervisor from Lynx Software Technologies (USA) to its automotive software stack. This technology significantly enhances ECU and vehicle computer security, providing safe system separation for the next generation of domain controllers and vehicle computer ECUs. This allows for hardware to be partitioned and isolated into different virtual machines so that software applications can co-exist while providing freedom from interference. Only with this technology can a clear and reliable separation be realized. The advantage: Software from different vendors and with different safety levels can be integrated on one ECU. If one element changes, only this element has to be tested again and not the whole ECU software.

ETAS is supporting LynxSecure with a version of its RTA-BSW AUTOSAR solution, RTA-VRTE AUTOSAR Adaptive Platform and an ESCRYPT embedded security solution to run within LynxSecure’s lightweight isolated virtual machine containers. This combination forms a complete software platform, supplied by ETAS, designed to address real-time automotive use cases that call for the highest levels of safety and security. It is good news for all OEM and Tier 1 stakeholders working on new E/E architectures, connected vehicles and other complex software systems.
