US: CTI NTCIP Signal Priority - SNMPv3/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: SNMPv3/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: SNMPv3/TLS standards include lower-layer standards that support secure center-to-field and field-to-field communications using simple network management protocol (SNMPv3); implementations are strongly encouraged to use the TLS for SNMP security option for this solution to ensure adequate security.

Solution Issues Severity: 4

The severity issue score calculation only includes issues associated with standards that are included by default.

Solution Issues:

DefaultSeverityNameTypeDescription
TrueLowUse TLS for SNMP OptionSecurity GapThe standard allows for multiple security mechanisms. The only defined mechanism that meets the requirements for C-ITS is the one based on TLS.
TrueMediumOut of date (medium)Standardization GapThe standard includes normative references to other standards that have been subject to significant changes that can impact interoperability or security of systems and the industry has not specified if and how these updates should be implemented for deployments of this standard.

Solution to Triples

This solution is used on the following information flow triples:
