Location Obscurer Proxy --> ITS Object:
auth certs
Definitions
auth certs (Information Flow): One or more authorization certificates for end entity use, which may be locked, and may be identification or pseudonym certificates.
Location Obscurer Proxy (Source Physical Object): The 'location obscurer proxy' (LOP) is a component of the CCMS that is responsible for hiding location information of an end entity from the registration authority.
ITS Object (Destination Physical Object): The general 'ITS Object' includes core capabilities common to any class of object.

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). |

Basis | There is no personal information in this, but the content is intended for a specific device (in many cases the device ID will be further obfuscated with a pseudonym). There is little to be gained by observing this content, though understanding the auth cert update frequency might be relevant to an attacker. | As the key credential for participation in cooperative ITS applications, this material must be correct and trustworthy. | Cert delivery must happen, but can be requested well in advance. |
