EU: CA Service - BTP/GeoNetworking/G5

Description:

This solution is used within Australia and the E.U.. It combines standards associated with EU: CA Service with those for V-X: BTP/GeoNetworking/G5. The EU: CA Service standards include upper-layer standards required to implement V2x cooperative awareness (CA) safety information flows. The V-X: BTP/GeoNetworking/G5 standards include lower-layer standards that support broadcast, near constant, low latency vehicle-to-vehicle and vehicle-to-infrastructure communications using the ETSI GeoNetworking Bundle over the 5.9GHz spectrum.

Relevant Regions:

• Australia
• European Union

Solution Issues Severity: 21

Solution Issues:

Default	Severity	Name	Type	Description
True	Low	Protocol features partly not applicable in the given context	Performance / Applicability Gap	A feature of the protocol is not fully applicable in the given context, e.g. GeoNetworking multi-hop forwarding in 5.9 GHz channels.
True	Medium	Overlap of standards	Overlap	Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow.
True	Medium	Security inadequate	Security Gap	The solution does not provide adequate communications security for the information triple, which potentially jeopardizes C-ITS operations.
True	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
True	Medium	Use case not considered in design (medium)	ITS Info Gap	While the indicated standards nominally address the information flow, the design may not meet practical constraints because this particular use case was not the focus of the design effort.
True	High	Draft not available (Critical)	Standardization Gap	The standards development organization has established a work item for the subject standard but a draft is not available for this critical feature to enable the interface. The draft may be missing due to the work item being new or simply a lack of activity on the work item.
