US: SAE Lane-Level Mapping - Secure Internet (ITS)

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Lane-Level Mapping with those for I-I: Secure Internet (ITS). The US: SAE Lane-Level Mapping standards include upper-layer standards required to implement lane-level and road furniture mapping information flows. The I-I: Secure Internet (ITS) standards include lower-layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

Solution Issues Severity: 4

Solution Issues:

Default	Severity	Name	Type	Description
False	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
False	Medium	Unvetted by community	Standardization Gap	The proposed solution uses a suite of standards that is accepted within some communities, but has not necessarily been accepted for use within the context of this information triple.
True	Low	Data not defined in standard format	ITS Info Gap	The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS.
True	Medium	Outdated security reference	Security Gap	The standard solution includes an outdated security reference.
