obu-firmware builds against vanetza-idf from microbu-esp32c5/external, but that tree was gitignored, so a clone of this repository could not build the firmware it ships. It is now committed here as ordinary files in its own folder, microbu-esp32c5/: the colleague's commit cf4b99f plus the V2X2MAP bridge's signature verification (--trust) used on the bench. Nothing is fetched from or pushed to the colleague's repository; this repository and its remotes carry everything. The folder's own .gitignore keeps build output, downloaded components and private key material out, as it did there; the committed file set is identical to that repository's tracked files. The ESP32-C5 is still flashed from obu-firmware/, which only takes vanetza-idf from microbu-esp32c5/, so the two stay separate folders. FLASHING.md says how to take a newer version of the colleague's tree (copy it over the folder, rebuild, test, commit).

EU CCMS CPOC L0 ECTL — RCA descriptive information
|

===================================================
|
|
|
|
Full Company Name / RCA Operator:
|
|
Hochschule für Angewandte Wissenschaften Hamburg (HAW Hamburg)
|
|
Urban Mobility Lab

RCA Name:
|
|
Urban Mobility Lab L0 Root CA

|

CertificateID:
|
|
0_Urban-Mobility-Lab-Root-CA_L0
|
|
|
|
Certificate HashedID8:
|
|
AFD566A8034ED5DB
|
|
|
|
CertificateID / acronym explanation:
|
|
- 0: CPA-ID reserved for the L0 environment.
|
|
- Urban-Mobility-Lab-Root-CA: Root CA operated for the Urban Mobility Lab at HAW Hamburg.
|
|
- L0: EU CCMS L0 research/test environment.
|
|
|
|
Purpose of testing:
|
|
The RCA is used for research, field testing and proof-of-concept activities of the
|
|
Urban Mobility Lab in the context of the micrOBU project. micrOBU investigates the
|
|
integration of vulnerable road users into C-ITS through development of a lightweight,
|
|
compact and low-cost VRU ITS-S using an MCU + mobile-phone architecture.
|
|
|
|
Contextual constraints / deviations:
|
|
- This is a new RCA and the first L0 submission for this RCA. No existing L0 entry is
|
|
intended to be replaced or revoked.
|
|
- The implementation, including the C-ITS protocol stack, signing functionality and
|
|
VRU Awareness Basic Service, is under active development. Full implementation
|
|
conformity is not claimed.
|
|
- The declared RCA Distribution Centre is the intended permanent DC URL. At the time
|
|
of this submission, the cits-dc.uml-hamburg.de subdomain and the required /getctl
|
|
and /getcrl endpoints are still being commissioned and are not yet operational.
|
|
- The RCA intentionally includes ITS-AID 638 (VRU Awareness basic service) with
|
|
bitmap SSP range 01/FF for L0 VAM/VBS research. ITS-AID 638 is a standardized ETSI
|
|
ITS-AID but is not contained in the current CPOC Protocol Release 3.3 Table 4 list;
|
|
its inclusion is therefore an intentional L0 profile deviation.
|
|
- The RCA private key is generated and maintained locally as an encrypted PKCS#8
|
|
NIST P-256 key for this L0 research environment. This software-based key storage is
|
|
not claimed to satisfy production/L2 cryptographic-module requirements.
|
|
|
|
Re-key / revocation / relationship to existing certificates:
|
|
New RCA / first submission. No existing L0 RCA certificate is affected.
