EU: Signal Control Messages - Secure Internet (ITS)

Description:

This solution is used within Australia and the E.U.. It combines standards associated with EU: Signal Control Messages with those for I-I: Secure Internet (ITS). The EU: Signal Control Messages standards include upper-layer standards required to implement signal control 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.

Relevant Regions:

• Australia
• European Union

Comm Profile: I-I: Secure Internet (ITS)

Comm Class: WAN - Wide Area Network

Solution Issues Severity: 16

Solution Issues:

Default	Severity	Name	Type	Description
False	Medium	Option not standardized	Standardization Gap	The option set includes at least one option that is not (yet) defined in a standard.
False	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
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	Low	Not a standard (minor)	Standardization Gap	The document is publicly available and widely used but it is not currently a formal standard.
True	Medium	Outdated security reference	Security Gap	The standard solution includes an outdated security reference.
True	Medium	Secure data access not provided	Security Gap	The solution does not define rules on how the application entity authenticates requests to accept or provide data.
True	High	Data/comm profile pairing	Standardization Gap	There are ambiguities as to how to (or if one should) couple the upper-layer standards defined in this solution with the indicated lower-layer standards.
