US: CTI NTCIP Signal Priority - SNMPv1/TLS

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: CTI NTCIP Signal Priority with those for I-F: SNMPv1/TLS. The US: CTI NTCIP Signal Priority standards include upper-layer standards required to implement field-to-field traffic signal control priority communications (e.g., for buses and emergency vehicles). The I-F: SNMPv1/TLS standards include lower-layer standards that define one way to retrofit basic security into SNMPv1 implementations (mainly in the US); however, this only secures the communications link and does not provide end-application security and is not recommended for new deployments.

Relevant Regions:

• Canada
• United States

Comm Profile: I-F: SNMPv1/TLS

Comm Class: MAN - Metropolitan Area Network

Data Profile: US: CTI NTCIP Signal Priority

Solution Issues Severity: 6

Solution Issues:

Default	Severity	Name	Type	Description
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	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.
