Leading the Embedded World


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

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 communicate with each other—with no human involvement—and influence life-critical decisions 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.

  • FIPS-140 Level 2 compliant Embedded Crypto toolkit

Security Credential Management System

The Platform for Secure Connected Car has been integrated and tested with the world’s first and only Security Credential Management System (SCMS). Ann ISS product, SCMS 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:
