Green Hills Platform for Secure Connected Car

The promise of a cooperative network of vehicles and smart cities envisioned in vehicle-to-anything (V2X) and European car-to-anything (C2X) depends on the underlying security and safety of wireless messages, on-board units (OBU) and smart city roadside units. The Green Hills Platform for Secure Connected Car combines the highest levels of multi-level security and ASIL safety with a mature V2X security toolkit, standards-based applications and cloud-based secure certificate management service.

No safety without security

Connected car technologies add another layer of intelligence to vehicles—the ability to "see" around corners and through other vehicles.

The connected car represents the next stage in the evolution of motor vehicle safety—going beyond vehicle-resident technologies like cameras, radars, and sensors. Connected car technologies add another layer of intelligence to vehicles—the ability to "see" around corners and through other vehicles. For the first time, unfamiliar vehicles and roadside units on untrusted public networks can communcate with each other—with no human involvement—and influence life-critical decistions and vehicle actions.

While the trio of functionality, performance, and safety formed the traditional foundation for automotive software, the connected car also demands authentication, identification, and separation of critical software components running in an insecure environment for the operational lifespan of the vehicle. In short, there is no safety without security.

Comprehensive safety and security for V2X

Over-The-Air Service (OTA)

The Platform for Secure Connected Car incorporates the ISS Device Lifecycle Management (DLM) OTA service that securely manages connected devices anywhere in the world.

The Platform for Secure Connected Car is a comprehensive solution for managed security credentials, OBU 1609.2 security, V2X safety applications and more.

V2X Applications

The Platform for Secure Connected Car supports V2X applications based on the architecture of specifications of ISO / ETSI / IEEE / SAE / C2C-CC, providing a modular framework and small footprint for various resource-constrained target platforms. For example, the Commsignia comprehensive V2X safety applications include:

  • Left Turn Assist (LTA)
  • Intersection Collision Risk Warning (ICRW)
  • Longitudinal Collision Risk Warning (LCRW)
  • Cooperative Forward Collision Warning (CFCW)
  • Road Hazard Signaling (RHS)
  • Pre-Crash Sensing
  • Blind Spot Warning
  • Stop Sign Movement Assistance

V2X OBU Security Toolkit

ISS and Commsignia offer a security toolkit for the on-board unit (OBU) to transmit and process secure messages and perform core security functions compliant to IEEE 1609.2-2016 and ETSI TS 103 097 standards.

  • Security service for IEEE 1609.3 WAVE networking services, including WAVE Short Message Protocol (WSMP) transmission and reception
  • Secure storage of V2V, V2I, C2C, and C2I certificates on the OBU
  • Secure boot
  • Software signing for secure transmissions
  • Over-the-air certificate top-offs over the vehicle’s lifetime
  • Securely maintain Credential Revocation List (CRL)
  • FIPS-140 Level 2 compliant Embedded Crypto toolkit

Security Credential Management System

The ISS SCMS is a high-assurance infrastructure for real-time generation of V2X certificates to protect digital assets across all lifecycle phases.

The Platform for Secure Connected Car has been integrated and tested with the world’s first and only Security Credential Management System (SCMS) from INTEGRITY Security Services is the de facto standard for securely delivering V2X and C2X digital certificates to OBUs. The Certificate Management Service addresses the US Department of Transportation (US DOT) announcement of New Proposed Rule Making (NPRM), Docket number NHTSA-2016-0126, delivering vehicle-to-anything (V2X) and European car-to-anything (C2X) certificates to automotive and smart city product manufacturers and operators worldwide:
