Collaboration to develop safer connected vehicles

A new collaboration has been established between ETAS and Lynx Software Technologies that aims to bring the automotive safety-critical world together with the highest levels of security to meet the demanding needs of the next generation of connected and autonomous high performance automotive systems. This technology integration was unveiled at last week’s embedded world exhibition in Nuremberg.

ETAS will provide and support the LynxSecure Separation Kernel for the automotive market. In addition, ETAS is supporting LynxSecure with a version of the RTA-BSW AUTOSAR solution and the ESCRYPT embedded security solution to run within the lightweight isolated virtual machine containers of LynxSecure. This combination forms a complete platform designed to address real time use-cases which demand the highest level of safety and security.

The LynxSecure Separation Kernel allows the microprocessor-based hardware to be partitioned and isolated into different virtual machines allowing software applications to co-exist while providing freedom from interference. The LynxSecure Separation Kernel technology also offers the LynxSecure Application virtual machine containers. These bare-metal virtual machines are efficient allowing application code to run directly on the microprocessor without the need for a guest operating system.

The demonstrator shown in partnership with Lynx at embedded world illustrated how the LynxSecure Application bare metal virtual machine technology is used to integrate the classic AUTOSAR environment provided by the ETAS RTA-BSW. The demonstration illustrated how existing AUTOSAR software can be integrated into a powerful DC/VC ECU, while providing the necessary safety, security and freedom from interference that the most demanding applications require. It can be seen how the safety critical LynxSecure Application partition running RTA-BSW and associated AUTOSAR application software continues to function, even when other virtual machine partitions are restarted.

The LynxSecure Application virtual machine containers will also be used to host the critical security components in strongly isolated partitions. This will allow security services such as intrusion detection, firewalls, key management, etc. to be separated from the rest of the system while providing a smaller trusted code-base footprint which is the foundation for ensuring the highest levels of security.
