What is the Security Credential Management System?
The Security Credential Management System (SCMS) is a unique security infrastructure that enables multiple vendors to operate in a safety-critical environment. Unlike conventional PKI systems that only support peer-to-peer connections, the SCMS architecture allows multiple devices from different vendors to exchange authenticated messages while preserving the privacy of vehicle owners.
How do vendors interface with the SCMS?
The standard interface devices use to communicate with the SCMS providers are defined by IEEE 1609.2.1, standard, published in 2022. The OmniAir test suite provides a consistent set of validation tests that confirm interoperability and compliance with this standard. Connected vehicle infrastructure operators can be confident that OmniAir Certified® devices can be successfully deployed with a compliant SCMS provider.
What is 1609.2.1?
It contains certificate management protocols that support the provisioning and management of digital certificates, as specified in IEEE Std 1609.2 TM. It ensures the end entities that devices use digital certificates to authorize application activities.
What Happens During a Test Session?
Participating vendors will have the opportunity for one-on-one test sessions with SCMS providers to help ensure readiness for certification and deployment. The private testing session is designed to familiarize vendors with relevant standards and OmniAir security test cases.
Participating vendors will learn from SCMS providers how to:
- Remotely accessing and loading test certificates.
- Enroll and authorize by the SCMS provider.
- Participants can also run through a select series of OmniAir’s security-focused 764b test specifications.
- Prepare your device for OmniAir certification.
The testing event will allow participants time between testing with each SCMS service provider to make any adjustments required to progress through the test process.
This process accurately emulated real-world security interactions between connected vehicles and security portals. For those passing through multiple security interactions, provides device manufacturers confidence that they are ready for OmniAir Certification and that they can deploy a secure OBU or RSU.
As with OmniAir Plugfests, only anonymized, aggregated test results will be published.
