Core SCMS Components

Overview

OpenSCMS implements the core functional entities defined by the IEEE 1609.2.1 Secure Credential Management System (SCMS) architecture. The primary SCMS components implemented in OpenSCMS are:

• Registration Authority (RA)
• Enrollment Certificate Authority (ECA)
• Authorization Certificate Authority (ACA)
• Linkage Authority (LA)

Among these components, the RA and ECA expose external REST APIs and act as ingress points for V2X clients. The ACA and LA are internal infrastructure services that do not expose public APIs and are accessed exclusively by other SCMS components.
