The Security Credential Management System (SCMS) Proof-of-Concept (POC) Implementation Project (SCMS POC Project) is being conducted by the Crash Avoidance Metrics Partners LLC (CAMP LLC) Vehicle Safety Communications 5 (VSC5) Consortium. Members of the Consortium are Ford Motor Company, General Motors LLC., Honda R&D Americas, Inc., Hyundai-Kia America Technical Center, Inc., Mazda, Nissan Technical Center North America, Inc., and Volkswagen Group of America. The goal of the SCMS POC design is to provide security services to support Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications at current production levels of passenger vehicles (up to 17 million annually) for the first year of deployment. An important goal of the SCMS POC system is to provide a flexible architecture that is capable of scaling to support larger numbers of V2V and V2I devices in the years following initial deployment. It is also anticipated that the SCMS POC design will provide both a stable platform and a research platform to support the USDOT and industry research needs prior to deployment. The work is sponsored by the National Highway Traffic Safety Administration (NHTSA) through Cooperative Agreement DTNH22-14-H-00449/0003.
Work in Task 4 of the project focuses on the design of the SCMS core components and protocols. Four software releases are planned during the course of the project. This document presents the requirements and specifications for the SCMS POC System Release 1.2 from the perspective of an End Entity (EE). This document is a work-in-progress. Future refinements and revisions to the requirements and specifications are anticipated as SCMS refinement is an ongoing task across multiple projects.
The following paragraph will guide you as an EE developer through this documentation highlighting requirements and API documentation in the order of an EE's lifecycle. If you implement your EE software following this guide, you should have a device at the end that is able to communicate with the SCMS throughout the whole lifecycle.
