Green Hills Platforms for Automotive:

The modern vehicle is becoming not just a rolling computer, but a rolling network. Software complexity and the number of vehicle networks—internal and external—are growing far beyond the traditional closed network, exposing life-critical vehicle domains to safety and security risks.

In recent years, the explosive growth of automotive electronics has fueled a revolution in the electrical networks within the vehicle. What started out as a closed CAN network on simple MCUs has become a complex system of operating systems and heterogeneous networks—some with IP addresses connected to the internet.

vehicle gateway controller is responsible for the fast and deterministic data routing and translation over networks between various vehicle domains such as ADAS or IVI. With the advent of the connected car, the modern gateway is now also responsible for acting as an intelligent gatekeeper for all data entering the vehicle and for secure over-the-air (OTA) software updates.

All in all, the gateway oversees internal networks (CAN, LIN, Ethernet, Ethernet AVB/TSN, DoIP, SOME/IP, RTP/RTCP, gPTP, FlexRay, MOST, HDMI, USB, DDS) and external networks (DSRC, cellular, satellite, WiFi, Bluetooth, Remote Keyless Entry) spanning all vehicle domains. Because some of this data is used by life-critical systems, the gateway must possess the highest security levels.

The gateway run-time software architecture must be safe, secure and scalable. The Green Hills Platform for Secure Gateway is built on INTEGRITY® real-time operating system (RTOS) technology, certified at the world’s highest safety and security levels. The certified INTEGRITY separation kernel isolates critical networking and security tasks from each other and from guest operating systems such as Linux and Android, running on the same core or multiple cores. In addition, AUTOSAR applications can be run in their own partitions, giving system designers more flexibility to build scalable systems.

• INTEGRITY RTOS—provides proven reliability and separation with unmatched Common Criteria EAL 6+ security credentials, ISO 26262 ASIL D safety certification and is incorporating the latest automotive cybersecurity standards as defined by ISO/SAE 21434 CAL 4 and UNECE WP.29 CSMS. INTEGRITY provides guaranteed system resources to assure CPU time and memory resources will always be available to tasks, even when faced with malicious or unintended events.

The Platform for Secure Gateway is integrated and tested with the Embedded Cryptographic Toolkit and network stacks from INTEGRITY Security Services (ISS) to protect device software, data, and communication. ISS offers a complete set of standards-based, platform-agnostic security protocols with FIPS 140-2 compliant, Suite B, cryptographic services for securing the modern gateway ECU:/p>

• secure boot, including trust anchor provisioning and software signing
• secure data-at-rest with encrypted key storage, integrated and optimized to the gateway processor
• secure network communication with SSL, TSL, IPSec, SSH
• secure OTA for digitally signed updates for gateway firmware

Safe and secure execution

The INTEGRITY RTOS and its Multivisor secure virtualization provide the certified separation and guaranteed hardware resources to applications and their AUTOSAR components, including safety and security tasks, drivers, middleware, guest operating systems and AUTOSAR operating systems. The resulting freedom-from-interference is a vital feature to safely and securely run these complex mixed-ASIL software components with determinism, across multicore heterogenous SoCs.

For AUTOSAR Classic, the INTEGRITY RTOS executes one or more AUTOSAR Classic environments in virtual address spaces/containers across one or more cores on a high-performance multicore application processor. No virtualization is required. This means customers have the flexibility to incorporate and run their own AUTOSAR Classic asset, an OEM’s AUTOSAR Classic asset or a third-party asset without compromising the platform’s performance, safety architecture or security.

For AUTOSAR Adaptive, Green Hills again leverages the INTEGRITY RTOS’ certified separation architecture and policies to natively run AUTOSAR Adaptive, as compared to other vendors that must rely on less secure virtualization for system separation. As a result, customers eliminate the significant complexities, performance overhead, security impacts, and development and debug challenges that come with using a hypervisor platform approach to AUTOSAR Adaptive in vehicle electronics designs.
