Registration Authority --> Linkage Authority:
linkage value request

Definitions

linkage value request (Information Flow): Request of authorization certificate linkage data, including linkage values and/or linkage seed (for revocation).

Registration Authority (Source Physical Object): The 'Registration Authority' (RA) is a component of the CCMS that is the main point of contact for an end entity, and is responsible for provisioning the end entity with authorization and successor enrollment

Linkage Authority (Destination Physical Object): A linkage authority (LA) is a component of a CCMS that provides inputs to the linkage value calculation process to enable efficient revocation of pseudonym certificates; using two linkage authorities preserves the privacy of an end entity against the authorization certificate authority.

Interoperability Description
Regional Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).
