obu-firmware builds against the vanetza-idf C-ITS library, which until now came from the colleague's microbu-esp32c5 tree beside the repository and was not tracked here, so a clone of this repository could not build the firmware it ships. The library alone is now part of obu-firmware, as obu-firmware/external/vanetza-idf: their external/vanetza-idf at commit cf4b99f, unchanged (9775 files; see its PROVENANCE.md). CMake takes it from there by default; -DVANETZA_IDF_DIR still points the build elsewhere. The rest of the colleague's tree (their own VAM firmware, PKI tooling, station-link Python tools, the V2X2MAP bridge) stays out of this repository and gitignored; nothing is pushed to their repository. NOTES.md, docs/06, TODO.md and the pcap verifier's usage line point at the new location.
Security
This is the security module of Vanetza. It implements the ETSI C-ITS security extension of the GeoNetworking protocol based on:
vanetza::security::v2namespace: ETSI TS 103 097 v1.2.1vanetza::security::v3namespace: ETSI TS 103 097 v1.3.1
Implemented Features
Most features are implemented, including:
- Security profiles including the CAM and DENM profile
- Certificate requests for unknown certificates of other stations
- Certificate validation for incoming messages
Missing Features
There are a few missing features, but the overall implementation is in a working state to send and receive secured messages. It has been verified to work correctly by interoperability tests with other implementations.
-
Revocation checks for certificate authorities
Certificates of CAs can be revoked via CRLs. There will be a new standard for the corresponding protocol in May 2018. It will be a new version of ETSI TS 102 941. -
v2: region checks for polygonal and identified regions
There areTODOnotes in the code ofregion.cppwithin theis_within()functions. Implementing these checks is non-trivial. -
v2: region consistency checks for regions other than circular and none region restrictions
There areTODOnotes in the code ofregion.cppwithin theis_within()functions. Implementing these checks is non-trivial. -
v3: region checks for identified regions
-
Certificate requests
Currently there's no support to request authorization tickets from an authorization authority or to do an enrolment.
