communication provider
provider of communication services used for the transmission of information
GNSS path post processing
evaluation
systematic examination of the extent to which an entity e.g. system, process, product, or a unit is capable of fulfilling specified requirements
access credentials
data that is transferred to on-board equipment (OBE), in order to establish the claimed identity of a roadside equipment (RSE) application process entity
NOTE Access credentials carry information needed to fulfil access conditions in order to perform the operation on the addressed element in the OBE. Access credentials can carry passwords as well as cryptography-based information such as authenticators.
point of observation
interface, or in general identifiable access to a system, where conformance can be stated and verified
assurance requirement
security requirements to assure confidence in the implementation of functional requirements
XML Encoding Rules
roaming rules
set of attributes for Front Ends according to CEN ISO/TS 17575-4, defining the group of associated EFC contexts and their relationships; and/or for Back Ends according to EN ISO 12855, defining the relations for multi-context EFC domains
empty list
container for attributeValues (OCTET STRING) with the length equal to zero
profile
set of one or more base standards and/or ISP, and where applicable, the identification of chosen classes, conforming subsets, options and parameters of those base standards, or ISPs necessary to accomplish a particular function
implementation conformance statement
statement made by the supplier of an implementation or system claimed to conform to a given specification, stating which capabilities have been implemented
HyperText Transfer Protocol
HTTP over Secure socket
toll service provider
a legal entity providing to his customers toll services on one or more toll domains for one or more classes of vehicles
NOTE 1 In other documents the terms issuer or contract issuer may be used.
NOTE 2 The toll service provider may provide the OBE or may provide only a magnetic card or a smart card to be used with OBE provided by a third party (like a mobile telephone and a SIM card can be obtained from different parties).
NOTE 3 The toll service provider is responsible for the operation (functioning) of the OBE.
proxy
optional component of the Front End that communicates with on-board equipment and processes road usage data into a format compliant with ISO TS 17575 and delivers the data to the Back End
average relative charging error
ratio between the sum of computed charges associated to a set of vehicles during a certain period of time and the actual due charge (for the same set of vehicles and the same period) minus 1
Element
DSRC directory containing application information in the form of attributes
target of evaluation
information security product or system for the subject of security evaluation
overview
attribute and group of data elements providing the information if an EFC context is relevant for a specific vehicle or not
acceptance testing
examination that a product, process, or service is in conformity with the system specification
accountability
property that ensures that the actions of an entity may be traced uniquely to the entity
associated EFC context
EFC context for which an individual user has the contractual consent that his or her Front End is interoperable
accepted charging error interval
interval of the Relative Charging Error varying from a negative (undercharge) to a positive (overcharge) value that the Toll Charger considers as acceptable, i.e. correct charging
test case
an abstract or executable test case
threat agent
entity that has the intention to act adversely on an asset
session
exchange of information and interaction occurring at a specific electronic fee collection station between the roadside equipment and the user/vehicle
relative time
point in time relative to a defined event e.g. the entrance of a vehicle into an EFC specific area in minutes and/or hours
relative charging error
ratio between the Absolute Charging Error and the actual value, i.e. Relative Charging Error = Absolute Charging Error/Actual Value
representative trips
trips that are of a distance larger than a defined threshold and so have to be considered by the related metrics
NOTE 1 Only trips which exceed the threshold and cover the specific types of roads of the Toll Regime have to be considered.
NOTE 2 The threshold may be defined as zero.
EFC regime
set of rules, including enforcement rules, governing the collection of toll in a toll domain
